Abstract

A pixelated bicontrollable metasurface tunable in the complete X band was designed with its meta-atoms comprising yttrium iron garnet (YIG)-patched pixels and conductive rubber (CR)-patched pixels on a metal-backed silicon substrate. Maximum absorptance of a normally incident plane wave greater than 0.99 is achievable and tunability with absorptance exceeding 0.9 is realizable, with the help of an external magnetostatic field and temperature. The YIG-patched pixels provide magnetostatic control modality with sensitivity of (Formula presented.) and the CR-patched pixels provide thermal control modality with sensitivity of (Formula presented.). The proposed metasurface absorber can be used to improve the performance of weather radar, police speed radar, and direct broadcast television.
