▎ 摘　　要

NOVELTY - Ultra-wideband polarization insensitive frequency selective surface absorber with stable oblique incidence comprises a second dissipation layer set from up to down sequentially a first power consumption layer and a grounding layer. The first energy consumption layer comprises a substrate made of Flame retardant (FR)-4 board. The upper surface of the two substrates are divided into several square units with the same size. The square unit of the substrate is corresponding up and down. Each square unit is printed with a first pattern graphene the ink printing ink, the first pattern is a square with a hollow circle. The center of the hollow circle is overlapped with the center of a square unit. Each square unit in the second consumption layer is printed on a second pattern by a graphene ink. The second pattern comprises a circular ring. The FR-4 plate upper surface is covered with layer of Perfect Electric Conductor (PEC) material USE - Used as ultra-wideband polarization insensitive frequency selective surface absorber. ADVANTAGE - The absorber further analyzes the function of the proposed structure based on the corresponding equivalent circuit model, verifies the polarization insensitivity and large angle absorption stability. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of a unit of an ultra-wideband polarization insensitive frequency selective surface absorber with stable oblique incidence.
