◎ Abstract :

For the last decade, metamaterials have rapidly transitioned from fundamental science to commercial technology, with waveguide-fed metasurfaces being a key development. Waveguide-fed metasurfaces are a new class of aperture antennas that combine the benefits of a traveling wave antenna with resonant metamaterial elements, thereby providing cost-effective array-like solutions for various applications such as computational imaging, wireless communications, radar, and wireless power transfer systems. Accordingly, analytical modeling of waveguide-backed metasurfaces has been the subject of active research interest for designing and optimizing metasurface antennas for applications at hand. In this talk, I will present a brief review of the dipolar modeling approach and how the approach has been tailored to allow the analytical description of metasurface apertures, thereby unlocking the potential for improved designs. This talk will also cover contemporary challenges with the design of metasurfaces for next-generation wireless systems and recent advances in developing the metasurfaces’ models to overcome these challenges.
