A Generalized Synthesis Procedure for Low-Profile, Frequency Selective Surfaces With Odd-Order Bandpass Responses

摘要: We present a generalized synthesis procedure for designing low-profile frequency selective surfaces (FSS) with bandpass responses of odd-order (N = 3,5,7,...). The FSSs designed using this technique use combination resonant and non-resonant sub-wavelength constituting unit cells cell dimensions periodicities in the order 0.15 λ0, where λ0 is free space wavelength. main advantage technique, compared to traditional FSS design techniques, that it allows ultrathin can provide sharp selectivity. An Nth typically has an electrical thickness ~ - 1) λ0/50 which significantly smaller than overall traditionally (~ λ0/4). proposed validated two prototypes having third- fifth-order responses. Principles operation, detailed procedure, implementation guidelines type are presented discussed communication.
