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.

In radiofrequency (RF) applications, reducing the structure size of the phase shifter (PS) other remains a key challenge. In this article, a new compact-wilds-phase shifter for reducing the size area of the conventional design has been introduced. Unlike, conventional shifter, the proposed one leverages metamaterial for size reduction by using complementary split ring resonator. It operates at central frequency 2.4 GHz. The experimental results showed that the proposed design can significantly reduce 66% from the size of conventional structure.
