Microwave seminar | 26 October 2020

Metasurface designs based on planar metallic geometries are the most promising approach for microwave, millimeter, and terahertz bands, where all-dielectric designs become quite thick and difficult to fabricate. In this talk, I will discuss recent work showing broadband and achromatic designs operating in these frequency ranges, limits on the achievable bandwidth, design techniques to overcome coupling between meta-atoms, and methods for achieving highly subwavelength meta-atom designs.
