摘要：

A simple synthesis method for ultra-thin double-sided cross-dipole-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) model in combination with closed-form expression is used to synthesize and validate the response of the proposed element. In addition, 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 size of the proposed unit cell is 0:4 lambda(0) x 0:4 lambda(0), where lambda(0) is the free space wavelength at the desired the resonant frequency. In addition, the fractional bandwidth for TE and TM modes is 10.42% at normal incidence. The measured results of a proposed FSS are presented and validated in comparison with the simulations with good agreement.
