| Research Abstract |
The rare-earth iron oxides is an indispensable element for microwave components due to its unique non-reciprocity. In this work, the magnet-less non-reciprocal magnetic gyrotropy realized by a traveling-wave resonator is proposed and studied both experimentally and theoretically. As a proof of concept, the developed theory has been applied to several microwave components including Faraday rotator, circulator, and isolator. The achievements are published as five journal papers, eleven conference papers, and two patents.
