Oblique incidence properties of the reflection coefficient of a multi-layered (or single-layered) metal-backed magnetic absorber (MA) are analyzed in terms of the input impedance. Constant input impedance, almost independent of the incident angles and polarizations, is achievable for most MAs. Thus, the incidence angle restriction for a specified level of …

Abstract: Oblique incidence performance of a novel two-layer absorb/transmit frequency selective surface (FSS) is investigated. The FSS has good frequency stability for both horizontally and vertically polarized waves incident normally or at oblique angles. Due to its transmission for 900/1800/1900 MHz mobile bands and good absorption for 5 GHz waves, it has the potential …
