SC-1: THz technology and instrumentation

Virtual Course

Presented by Dr Miguel Navarro-Cia

Date and Time: Sunday, July 5, 08:00 - 12:00

Abstract: The terahertz gap (0.3 – 3 THz) remains still an underused electromagnetic spectral band sandwiched between conventional electronics and optics. It holds promise however for many applications ranging from high-speed wireless indoor communication, high-resolution imaging, security screening and molecular spectroscopy.
For all these applications, THz technology needs to be developed to the standards of microwaves and optics. In this quest, engineers need to be well aware of the current technology and the challenges related to THz in order wangle the next generation of THz components and systems.
This Short Course aims to provide an opportunity for attendees to familiarize with THz technology (CW and pulsed) and dig into the reasons why THz technology lags behind. The storyline of the Short Course will build upon the presenter’s experience with the commercial instruments: (CW) ABmm vector network analyser and TeraSense Tera-1024 imaging system; (pulsed) Teraview Spectra 3000 and Menlo TERA K15 spectrometers, and with an in-house (University College London) near-field time-domain spectroscopy system.

SC-4: Integrating Electromagnetics and Communications: Teory and Practice Through Massive MIMO, 5G, Reconfigurable Surfaces and Beyond

Virtual Course

Presented by Said Mikki and Debdeep Sarkar

Abstract: We provide a fully integrated treatment of communication and electromagnetic theories, where the physics of electromagnetic fields when viewed as spacetime processes is directly linked to signal processing, information, and energy transfer in wireless links. Utilizing general and powerful theoretical tools developed in recent researches, such as the antenna current Green’s function, energy localization in spacetime, the cross-correlation Green’s functions, the infinitesimal dipole model (IDM) techniques in machine learning, we explicate how information capacity, correlation, and energy transfer are influenced by taking into account the full physical content of EM fields as spacetime signals in concrete applications, including spectral efficiency enhancement, diversity gain optimization, engineering MIMO channels using metasurfaces, and dispersion management in large and complex arrays. Various case studies in massive MIMO, 5G, and Future Antennas are introduced to illustrate the main advantages and novel new applications in a pedagogically illuminating manner.

Virtual Course

Presented by Hisamatsu Nakano

Abstract: Modern radio-wave communication systems require an antenna to have special capability, such as beam-steering capability, null field-forming capability, or tilted beam-forming capability.

SC-9: Gap waveguides for mmWave antenna systems and RF system Integration

Access to be provided directly to participants

Presented by Ashraf Uz Zaman and Eva Rajo-Iglesias

Date and Time: Sunday, July 5, 13:00 - 17:00

Abstract: There is an emergent need for higher data rate related to upcoming wireless applications. Given the data rate, capacity and quality of service (QoS) requirements, this can only be possible if the vast unlicensed bandwidth available at mmWave frequencies can be utilized and all the technical hurdles at mmWave frequencies (above 30 GHz) are solved in a cost-effective way. In terms of available bandwidth world-wide, flexible transmission rules, 60 GHz is a boon from a system perspective. But RF designers have faced enormous challenges in simulation, design, integration, physical realization, packaging and test of the complete systems. The technical challenges are literally orders of magnitude more complex than 2.4 GHz or 5 GHz Wi-Fi systems of today.
The gap waveguide technology has the potential to be used as a low-loss mmWave technology. The main advantages of the gap waveguide structure are as follows: Gap waveguide is a waveguide where EM wave can be guided and controlled even in an oversized parallel-plate structure. The waveguide can be realized without any requirement of metal contact between the upper metal surface and the lower surface, and thereby allowing cheap manufacturing of low-loss waveguide components at mmWave frequency bands or even higher. The relaxed mechanical requirements pave the way for low or moderate precision machining, lower fabrication time requirements and may even make possible the usage of some low cost fabrication techniques such as injection molding, and plastic hot embossing. The short course will present an overview of the gap waveguide technology with focus on mmWave high efficiency antennas and integration of RF electronics with the proposed antennas.

Abstract: Machine learning is a method of data analysis that automates analytical model building. As the antennas are becoming more and more complex each day, antenna designers can take advantage of machine learning to generate trained models for their physical antenna designs and perform fast and intelligent optimization on these trained models. Using the trained models, different optimization algorithms and goals can be run quickly, in seconds, for comparison and for types of different studies, such as for example stochastic analysis for tolerance studies etc.. This short course presents the process of fast and intelligent optimization by adopting both the Design of Experiments (DOE) and machine learning. Examples to showcase the advantages of using machine learning for antenna design and optimization will be presented.
