A new generation of metasurface antennas

Abstract: “Metasurface” (MTS) denotes a surface constituted at microwave frequency by PCB or 3D printed elements small in terms of wavelengths that collectively exhibits equivalent homogeneous boundary conditions to any interacting electromagnetic fields. MTSs have had and are having a strong impact in Antenna applications. In the years 2000-2010 MTS for antennas were essentially uniform in space and realized by periodic printed elements.  This was the first generation of MTS. In the second generation (2010-2020), MTS for antennas was constructed in such a way to change boundary conditions in space and control the scattered field. Today we are facing a transition to the third generation of MTS antennas, where MTSs change boundary conditions in space and time, opening new perspectives in 5G communications and beyond. In this presentation, the evolution of MTS antennas is described, with new ideas and examples on future communication scenarios.

Advances in Computational and Experimental Bioelectromagnetics for Healthcare: Sensors and Neurointerfaces

Abstract: Although technical challenges are still daunting, the clinical utility of neuroprosthetics has increased dramatically over the past few years. This has been accomplished through the convergence of numerous disciplines, which have individually added fundamental understanding/capabilities to systems that interface with the human body to restore senses and movement, or treat prevalent diseases that have currently no foreseeable cure. Among these, predictive multiscale computational modeling methods have greatly aided in the design of neuroprosthetics by embracing the complexity of the nervous system, which span multiple spatial scales, temporal scales, and disciplines. In this talk, we will cover some of the recent advances in bioelectromagnetic systems for healthcare, with a particular focus on visual and hippocampal prosthesis, peripheral neuroprosthetics, and sensors.


Gianluca Lazzi, PhD MBA is a Provost Professor of Ophthalmology, Electrical Engineering, Clinical Entrepreneurship and Biomedical Engineering at the University of Southern California (USC) where he is also the holder of the Fred H. Cole Professorship and the Director of the Institute for Technology and Medical Systems (ITEMS), a joint initiative of the Keck School of Medicine and the Viterbi School of Engineering. His expertise is in antenna design, medical applications of electromagnetics, implantable devices, neuroengineering, wireless telemetry, and liquid metal sensors. He is a Fellow of the IEEE, a Fellow of the American Institute for Medical and Biological Engineering (AIMBE), and a Fellow of the National Academy of Inventors (NAI). He co-founded Teveri, Inc, which is focused on the commercialization of stretchable conductive liquid metal-based fibers knitted in clothing and athletic apparel to bring seamless biometric, sensing and illumination solutions to smart clothing as well as stretchable electronic systems for medical, consumer, and military applications. He is the 2022 President of the IEEE Antennas and Propagation Society.

New Trends in Antenna Design using Gap Waveguide Technology

Abstract: In this talk, a brief overview of the fundamentals of gap waveguide technology and a summary of classical designs of directive antennas based on corporate fed arrays will be first presented. After that, some new options for using this technology in the millimeter frequency bands will be presented. This includes the use of alternative periodic structures instead of the classical bed of nails, as well as the

potential of this technology to be combined with classical technologies such as microstrip and the design of other kind of antennas as for instance leaky wave antennas. In this way, an overview of different on-going research lines connected to this technology will be presented.
