Design and Evaluation of EM Shielding Materials Consisting Metal Wire Arrangement Structures

Abstract

Recently, EM shielding materials and EM absorbers for high-frequency range are rapidly required. In this study, the metal wire arrangement sheets are proposed as newly frequency selective EM shielding materials. We compared with measured transmission coefficients in free space and calculated values by FDTD method (2 GHz - 100 GHz). Furthermore, the transmission coefficients of proposed EM shielding sheet having two resonant frequencies were measured from microwave to millimeter-wave band.
