Manipulating Propagation and Scattering of Microwave by Optically Transparent Metasurface

In this paper, metasurfaces with optical transparency is proposed to control either the propagation or the scattering of microwave. Specifically, we have designed a band-pass frequency selective surface (FSS) with a transmission window around 1.6 GHz and a coding metasurface for suppressing the backward scattering with broad working band from 7.8 to 15 GHz. The proposals provide new opportunities to tailor the microwave propagation and scattering with simultaneously high transmittance in visible frequencies, which could offer many benefits in practical uses, such as window and solar panel applications.
