Abstract：A three-dimensional Absorptive Frequency-Selective Transmission(AFST) structure with dual absorption bands is proposed, which is composed of a metal strip embedded with chip resistors and a parallel plate waveguide structure.The structure can realize characteristics of absorption-transmission-absorption, that is, there is an absorption band on each side of the passband, and each absorption band contains two reflection zeros.The equivalent circuit model of the structure is derived, the design concept is studied and obtained through simulation.The results show that the performance remains stable under oblique incidence.The effectiveness of the proposed equivalent circuit model and the frequency selection characteristics of the designed AFST structure are verified.
