Abstract

A slotted-circle patch metasurface that can efficiently absorb electromagnetic (EM) waves in three different bands is proposed. Simulation results show that the proposed structure can absorb signals in three different bands, namely at 8.10 GHz, 15.39 GHz and 19.7 GHz with absorption peaks of 99.8%, 99.7% and 99.8%, respectively. The 2-mm thick absorber is electrically thin, corresponding to λ/18 at its lowest operating frequency. The absorber can be used in many applications such as anechoic chambers, scattering control, photodetectors, microbolometers and solar cells.
