In this paper, we introduce a new ultra-thin microwave absorber made by a proper array of split-ring resonators (SRRs). And we propose that while using vertical split-rings cells to replace the single split-rings cells, the polarization dependence can be avoided and the absorption can be extended to the case of oblique incidence. Furthermore, we studied how to get multi-band absorber or expand the...
In this paper, two kind of microwave absorbers based on local resonance of artificial periodic structures i.e. metamaterials. When irradiated by plane wave with adaptive polarization, there will be electric or magnetic local resonance in the metamaterials. To absorb the microwave energy been reflected, resistive sheets are used like conventional Salisbury screen. The absorber based on electric resonance...
