|This article aims at discussing a computational approach to designing 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 a biased transistor loaded in the gap of circular ring resonator. Based on the derived mathematical model, co- and cross-polarized components have been extracted, which helps (cid:12)nd Faraday and Kerr rotation…

Microwave Nonreciprocity

It is shown that the recently emerging proposals to achieve magnet-free nonreciprocity with linear, periodically time-varying circuits can compete with traditional ferrite devices and even outperform them in several metrics, thus opening the door to exciting venues for miniaturized low-cost and high-performance non Recursion devices with numerous applications ranging from full-duplex communications and quantum computing to biomedical imaging and radar systems.
