Metasandwich ferrite plate/wire grating/longitudinal copper strip with varactor to achieving controlled microwave nonreciprocal absorption

摘要

Three-layer metasandwich ferrite plate/periodical wire grating/varactor-loaded orthogonal asymmetric strip is proposed, realized and investigated experimentally in rectangular waveguide at microwaves. It has been shown that metasandwich possesses electrically/magnetically controlled nonreciprocal microwave resonant absorbing of linearly polarized magnetic field of incident wave and not strong forward losses under multi-coupled resonances.
