Abstract
AbstractAn innovative all‐metal self‐support microwave metamaterial absorber (MMA) based on a continuous complementary split ring resonator (CSRR) array frequency selective surface (FSS) is constructed. The CSRR‐based FSS has a selected frequency of 23 GHz and is proved to be polarization insensitive. And the all‐metal MMA has the same response frequency as the FSS, showing convenience in the geometrical scaling process. Additionally, in both transverse electric and transverse magnetic modes, the all‐metal MMA shows stable response at oblique incidences with an incident angle as large as 50°. Along with lightweight, easy fabrication and high cost‐performance ratio, the new proposed all‐metal FSS‐based MMA has good potential to serve in many practical applications.
