Multifunctional Nonreciprocal Metasurfaces Based on Spatiotemporal Modulation

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

In this talk, we put forward the concept of multi-functional nonreciprocal metasurfaces realized on an universal hardware platform. The proposed prototype is based on a spatiotemporally modulated impedance surface. We show that using appropriate traveling wave modulations it is possible to realize various nonreciprocal properties controlling the response for illuminating plane waves. Based on this principle, we find proper modulation functions for different application purposes, which allows us to switch the device functionality among isolators, phase shifters, circulators, and potentially even more functionalities.
