A metasurface absorber based on the slow-wave effect has the advantages of long interaction time and high absorption. A slow-wave metasurface absorber is constructed using the periodic arrangement of the Jerusalem cross, which achieves a reflectivity of −15.0 dB at 5.0 GHz. Furthermore, dual-frequency absorption is …
