Compact FSS Absorber Design Using Resistively Loaded Quadruple Hexagonal Loops For Bandwidth Enhancement

The design of a thin microwave absorber which exhibits a −10 dB reflectivity bandwidth of 108% at normal incidence and 16% for simultaneous suppression of TE and TM polarised waves over the angular range 0–45° is presented. The structure consists of a 3 mm-thick metal backed frequency selective surf...
