Cloaking and Transparent Metasurfaces with Anapole and Pseudo-Anapole States

Split Ring Resonators (SRRs) are a promising architecture in order to design cloaking and transparent metasurfaces. According to the multipole decomposition, electric, magnetic and toroidal dipoles are induced on each SRR forming the so called anapole state for cloaking purpose and pseudo-anapole state for transparency. Results for both cases are experimentally validated using microwave measurements in an anechoic chamber facility.
