Ultra Thin Resistively Loaded FSS Absorber For Polarisation Independent Operation At Large Incident Angles

In this paper we report on a resistively loaded Frequency Selective Surface (FSS) absorber design which is insensitive to the polarization of microwave signals incident at angles of 45º ± 5º. The metal backed periodic structure is composed of an array of conductive rectangular loops, each loaded wit...
