Reduction of electromagnetic interference in HF circuits by improving the effectiveness of shielding structures

Mohamed Hajji, Ahmed Nouainia, Taoufik Aguili

Abstract

Because of the substantial development of electronics and telecommunication technologies, materials that exhibit good electromagnetic interference shielding performance are important for alleviating the impact of interference induced by a remarkable variety of devices. There is thus currently great research interest in enhancing simulation tools and developing new techniques to protect electronic installations against such electromagnetic coupling. However, various numerical methods that are used to treat such electromagnetic problems are rapidly reaching their limits in terms of central processing unit (CPU) time and memory storage requirements. We therefore propose herein use of the method of moments (MoM)–generalized equivalent circuit (GEC) approach based on the wave concept as a convenient simulation tool to study structures designed for such shielding applications, considering the cases of both perfect and lossy metallic shielding surfaces. The shielding efficiency is optimized for each case based on a parametric study of structural parameters. We then numerically study the effect of the type of material used to introduce losses for shielding, modeled based on the surface impedance \({Z_\mathrm{s}}\) . The numerical results are validated against other methods.
