A Multi-Functional Reconfigurable Metasurface: Electromagnetic Design Accounting for Fabrication Aspects

In this paper we present the theoretical considerations and design evolution of a proof-of-concept reconfigurable metasurface, primarily used as tunable microwave absorber, but also wavefront manipulation polarization conversion device in reflection. We outline all taken into account, from selection patch shape, unit cell size, substrate, to topology structure that realizes desired tunability. The presented conforms fabrication restrictions is co-designed work with an integrated circuit chip for providing complex loads using commercially available semiconductor process. proposed can perform multiple functionalities by appropriately biasing circuit: Perfect absorption wide range incidence angles both linear states, accommodating spectral vicinity 5 GHz, potential control, exemplified via anomalous reflection conversion. end vision such be scalable deployable practical HyperSurface, i.e., intelligent multi-functional metasurface capable concurrent functionalities: absorption, beam steering, conversion, shaping, holography, sensing.
