Metastructures as Computing Machines

In order to structure and control waves, we need materials.  By judiciously engineering material media, one can manipulate and tailor waves to achieve novel functionalities.  One of the interesting thrusts in exploring the utility of structuring waves is in ultrafast computing.  Can one envision specially designed metamaterials that can function as analog computing machines?  The answer to this question is indeed “yes”.  In recent years, we have been exploring how such metamaterials and metasurfaces can be designed and constructed in order to provide wave-based, material-based, ultrafast analog computation.  We have shown, theoretically and experimentally, how such metastructures can solve integral and differential equations, can invert matrices and can indeed achieve optimization when waves enter into them.  In this talk, I will give an overview of our recent work in this area, will discuss some of the results, will explain physical insights into their functionalities, and finally will forecast possible future research directions in this field.

Millimeter Wave Integration and Packaging Strategies Using Antenna-in-Package

Affordable and high performance front end modules (FEMs) have been identified as key research challenges for next generation millimeter wave communications. While the design of active components and sub-systems has been explored by many research groups, there is still a need to provide integration and packaging strategies that can meet system requirements and not inhibit the performance obtained at the wafer level. This poses challenges on the front-end modules (FEM) to deliver innovative packaging solutions which can fulfill the FEM integration requirements to maximize performance. Antenna-in-package (AiP) is a key technique that will enable the realization of 6G FEMs. The talk will discuss AiP solutions from a multi-disciplinary research team and will highlight the design, modeling, and characterization of planar antennas integrated into enhanced quad flat no-lead (eQFN) packages in WR8 and WR5 frequency bands. Further, the design, modeling, and simulation results of chip-to-package transitions, transmission line structures, and antenna feed elements are discussed. The simulated bandwidth and gain of the integrated antennas is compared with their standalone versions. To facilitate accurate design of the antennas and packaging transitions, high frequency material characterization has been conducted to obtain dielectric properties of the over mold materials. A workflow to characterize fatigue failure under board level vibration will be introduced with simulation results indicating the potential locations of solder failure under vibration. Validation of simulation results is conducted using fringe projection to directly measure the vibration mode when a printed circuit board is under vibration.

Applications of exceptional points of degeneracy in RF

We discuss an important class of degeneracies that occur when two or more eigenstates of a system fully coalesce. Such exceptional degeneracies happen in circuits, resonators, and multimode waveguides. These exceptional points degeneracies (EPDs) involve the polarization states and occur in a surprisingly large number of systems, like fully passive systems or in systems that include gain elements.

We provide various experimental verifications of the occurrence of EPDs in circuit resonators and waveguides. We discuss possible applications in antennas, antenna arrays, oscillators, delay lines, etc. Important applications are in extreme sensitivity for sensing, extreme tunability, purity and robustness of oscillation in circuit oscillators, very high-power generation, etc.

We discuss how EPDs are useful to conceive highly sensitive sensors. Indeed, it has been apparent that resonant frequencies in a system with EPD are extremely sensitive to a perturbation. Therefore, the detection of a large frequency shift in a resonator or in an oscillator is an indicator of an applied physical, chemical or biological perturbation. Systems of EPDs can be realized using gain and loss (usually referred as EPDs induced in PT symmetric systems), time modulation of a component, etc. We will provide the experimental demonstration of such extremely sensitive systems.

Huygens’ Metasurfaces for Precise Antenna Beamforming and Beamsteering

We will describe the concept of the Huygens' metasurface which comprise co-located electric and magnetic dipoles forming an electrically dense array of Huygens' sources or scatterers. These engineered surfaces can be designed to control electromagnetic waves at will. Unlike traditional antenna transmitarrays, Huygens' metasurfaces can be made sub-wavelength thin and deprived of spurious Floquet modes, while preserving excellent matching characteristics. Huygens' metasurfaces can be used to manipulate the phase, magnitude and polarization of incident electromagnetic waves, including those from nearby elementary antennas, for a variety of applications. For example, Huygens' omega bi-anisotropic metasurfaces enable wave refraction at extreme angles without any reflections. We will review progress of such Huygens’ Metasurfaces for antenna beamforming and beamsteering. Examples to be discussed include high aperture efficiency/low-profile antennas, antenna aperture beamforming with simultaneous magnitude and phase control, and electronic beam steering.

Metrological Traceability

Metrological traceability requires a documented, unbroken chain of calibrations to specified reference standards, including the stated measurement uncertainties.  Ideally the references are national or international standards that are realizations of the measurement units of the International System of Units (SI).  This makes the calibration traceable to the SI through an organization or laboratory, and not traceable to the organization or laboratory.  Requirements and methods for establishing metrological traceability are defined in international: standards, laboratory accreditation cooperatives, and metrology organizations.  With the intent to provide confidence in consistency and comparability of global measurements.  The methods used for establishing traceability will be presented.

Unlocking potentials of LIS via new material and antenna technologies

A key technical challenge arising from industry is to develop autonomous and reconfigurable systems which integrate communication, sensing and computing functionalities, operating and delivering effects in contested domains. The talk will provide a summary of scientific research related to above objectives. I will describe our research in three themes, namely, material discovery and machine learning; smart materials fabrication and characterisation; large intelligent surface (LIS) and new antenna theories.


Especially one of limiting factors in the design of LIS is the use of tunable materials. Currently, almost all LISs are designed based on conventional PIN diodes/varactors, a technology developed in 1970s, which cannot be readily scaled up for 6G. We have proposed a new concept of formula graph that unifies structure-based and structure-agnostic materials descriptors enabling us to design a general GNN architecture for materials property prediction.


Finally, the current design strategy of LIS and large antenna arrays was restricted to the topology with periodic, aperiodic, and random distributions. We have theoretically and experimentally reported that the array with hyperuniform disorder exhibits extraordinary directive emission and scanning features, while being scalable for extra-large arrays without any additional computational effort.

Channel Modelling for THz Communications

THz communications is one of the physical layer candidates for the upcoming 6th generation of wireless systems. Although the propagation channel at sub-THz frequencies has similarities to those at Millimeter waves, the higher path loss, the required higher antenna gains and the smaller wave lengths and the operational environments coming along with new applications are calling for specific channel models. For the standardisation process appropriate channel models for the various applications are required. Corresponding channel modelling activities are ongoing at ITU-R, IEEE 802 and in the recently established ETSI ISG THz. In this talk a brief overview on the status of channel models for THz communications focussing on the needs for standardisation bodies will be provided. This includes a review on relevant propagation phenomena, results from measurement campaigns, already existing channel models and a summary of requirements on channel models for future applications.

Design Challenges and Opportunities in Car Antenna Systems

For many years, car antennas simply imply protruding wires on car bodies that are used for receiving broadcast radio signals. In recent years, many more antenna systems are packed into cars to support new applications and services, including GNSS, Wi-Fi, LTE, SDARS, long/mid/short-range radar, etc. These antennas are challenging to design due to a wide variety of design requirements and constraints. To make things worse, industrial designers want antennas to disappear from the car body altogether. In this talk, I will overview the evolution of car antennas and how the design of these antennas become increasingly challenging. I will then introduce some recent innovations in car antenna design to address the challenges in different use cases. As a representative example of an interesting research problem that benefits from an innovative approach, I will detail the systematic design procedure of a Vehicle-to-Everything (V2X) antenna system that can provide the required line-of-sight coverage, despite being a hidden antenna solution. Going higher up in frequency, I will also introduce our recent design of a 79 GHz series-patch array, which is intended for future cars’ multiple-input multiple output (MIMO) radar.

Recent Advances in Robotic Antenna Measurements

Traditional antenna test facilities are typically designed with a specific measurement application in mind, and as a result these facilities tend to be comprised of single fixed measurement geometry.  However, modern antenna measurement ranges employing multi-axis robotic positioners provide a near limitless degree of re-configurability in terms of measurement types and scan geometries. This drives an ongoing need to evaluate each unique setup and application.  This previously unimaginable flexibility offers new opportunities for the improvement of safety, measurement quality and reduction of measurement uncertainties. These new robotic systems are capable of acquiring large amounts of special data allowing for the implementation of advanced post processing techniques.  Model based Systems Engineering and development (MBSE/MBD) approaches can be employed to dramatically reduce the time, effort and cost associated with the test development and validation phases of a given program.  MBSE tools can also be used to optimize test configurations to greatly reduce measurement uncertainties and simulate measurements.  This presentation provides an overview of how these engineering techniques are being harnessed during the implementation of a new dual multi-axis robotic antenna test system.

The future challenges of ionospheric tomography and data assimilation with applications for communication and navigation systems

The ionosphere has been studied extensively; notably in the early days by Appleton who coined the term ‘space weather’. This term denotes the variability in the ionospheric propagation environment because the medium is driven, both electromagnetically and mechanically, by constantly changing solar and terrestrial activity. There are many electromagnetic sensing instruments that can measure the ionosphere and help to characterise it in an instant, however they are not sufficiently accurate, numerous or widely distributed to provide observations that can be interpolated into a highly accurate 3D specification. 


There is no single instrument to provide a 3D specification of the Earth’s ionosphere at spatial scales of metres and temporal scales of seconds across a large region of continental/global scale.  However, there are techniques to obtain electron density maps out of line-integral observations (tomography) or to merge models and observations together (data assimilation).  The talk will describe the current state of the art and the upcoming requirements based upon the likely needs of future communication and navigation systems.

Wireless power transfer via magnetoinductive waves


The concept of magnetoinductive (MI) waves was introduced two decades ago in the context of the emerging field of metamaterials as slow waves that can propagate by virtue of magnetic coupling between individual meta-atoms. Changing the resonant frequency of the meta-atoms and the coupling between them, the dispersion of MI waves can easily be tailored enabling a large variety of applications of MI waves ranging from near-field guiding and imaging to superdirective antennas. In this talk we focus on wireless signal and power transfer in magnetoinductive structures. We look at a variety of scenarios, including power splitting and guiding, switchable unidirectional signal transfer, wireless power transfer in the presence of radiation, in the presence of a conducting environment, or via coupled evanescent magnetoinductive waves.

Site-Specific Radio Channel Modeling in Cyber-Physical Wireless Emulator

Design, evaluation, and verification of a large-scale wireless system with high accuracy is essential prior to the implementation.  Stochastic channel models are utilized for the link level and system level simulations for the performance evaluation, and the exhaustive drive-testing method is deployed for the validation. The former technique can be applicable for intra-system evaluation, but not suitable for inter-system coexistence in the realistic scenarios.  The latter technique is time and cost inefficient.  A cyber physical wireless emulator is developed to overcome drawbacks of both of these approaches. It emulates the real-world wireless network scenarios in real-time, not only within cyber space but also with real or prototype radios via physical interface.  Hence, scenario-based radio channel modeling framework is necessary for the implementation of the cyber-physical wireless emulator, which should have site-specific and system-independent features in either local/wide and stationary/dynamic scenarios, and which generates continuous and spatially-consistent channel responses.

This invited talk presents the concept of cyber-physical wireless emulator in brief, and explains how the dynamic channels are modelled within the real-time emulator in site- and scenario-specific manner, considering antenna directivity, multipath fading, shadowing by moving objects, death and birth of clusters, and large scale path loss. The work has been conducted under the contract JPJ000254 with the Ministry of Internal Affairs and Communications of Japan.

UWB Future 5G Transceivers & Wearable Electronics

Future communication links (future 5G) will require higher data rates, multiple beams, and higher transmit/receive gains, in addition to smaller weight, cost, and power. With the growing interest for reduced size platforms and the requirement for ultra-wideband (UWB) performance to address multi-functionality, there is a strong need for UWB RF front-ends with ultra flexible interfaces. The latter will include millimeter wave and THz capabilities to enable increased spectral efficiency, multi-functionality and security. Simultaneous transmit and receive (STAR) transceivers are also becoming a focus for the coming decade. 

Further, in recent years, a variety of flexible fabric-based electronics have been proposed. To this end, our team proposed a new class of conductive textiles that have demonstrated unique capabilities in terms of flexibility, durability and manufacturing-ease using standard automated embroidery machinery. These electronic threads (E-threads) have the capability to generate fully embroidered microwave circuitry that has the same electrical properties as traditional microwave circuits printed on PCBs. As such, a new class of wearable devices that are fully integrated and inconspicuously placed within clothing is possible.

This presentation will focus on innovative methods for handling UWB communications with RF front end and back-end capabilities having historically low power and game-changing frequency-independent operation. They will include low power MIMO and beamforming across large bandwidths, from MHz to millimeter wave bands. Challenges in realizing future textile-based electronic devices, including wearable wideband transceivers will be presented. Among them, reliable wearable interconnects, chipsets that are less bulky and integrated with the textile circuitry, and manufacturing challenges will be discussed.
