Space-Time Metasurfaces: Analysis, Design and Applications

Abstract

We review the recent progress on wave transformation by space-time metasurfaces. Firstly, analysis of wave incidence to various space and time interfaces, and periodic space-time metasurfaces is provided. Then, design, full-wave simulation and experimental demonstration of space-time metasurfaces are presented. Some of the exotic applications of metasurfaces are also introduced. In particular, we provide the experimental results for a perfect mixer-metasurface where undesired mixing products are strongly suppressed.
