A novel design of absorptive frequency selective surface (AFSS) with tunable absorptive/switchable transmissive property is presented. The AFSS is comprised of a resistive surface and a metallic bandpass FSS on which PIN diodes are mounted. By changing the working state of the PIN diode, a tunable absorption performance at 3.5–11.2 GHz is achieved with a switchable transmission at the frequency of 0.83 GHz. A prototype of the proposed structure is fabricated and measured under the normal incidence.
