Abstract

This article aims at discussing computational approach to design magnet-free nonreciprocal metamaterial. Detailed mathematical derivation on floquet mode analysis is presented for Faraday and Kerr rotation. Non-reciprocity in the designed metasurface is achieved in the presence of biased transistor loaded in the gap of circular ring resonator. Based on the synthesized mathematical model, We extract co-cross polarized components as well as Faraday and Kerr rotation from the developed synthesized model and compare/contrast reciprocal and nonreciprocal system.
