Performance limits of metasurfaces for microwave, millimeter wave and terahertz bands

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.
