Synthesis of Planar and Conformal Single-Layered Double-Sided Parallel-Cross Dipole FSS Based on Closed-Form Expression

Abstract

A simple synthesis method for ultra-thin double-sided cross-dipoles-based Frequency Selective Surfaces (FSS) is presented in this paper. The presented technique is used to design a flexible band-stop FSS for Electromagnetic Interference (EMI) shielding applications operating at 10 GHz. An Equivalent Circuit (EC) combined with a closed-form expression is used to synthesize and validate the response of the proposed element. Further, a parametric study of the proposed FSS aiming to optimize the bandwidth has been presented. The proposed FSS holds similar responses for TE and TM mode of polarization at normal incidence. Further, the conformal behavior of the proposed FSS in comparison with planar FSS is presented and evaluated. The proposed FSS is validated with the full-wave EM solver for simulation, and a prototype is fabricated. The measured results of a proposed FSS are presented and compared to the simulations with good agreement.
