Abstract: In this paper, a spatial and frequency selective electromagnetic shield, employing an anisotropic metamaterial device, is analyzed and developed. The results are based on a numerical analysis using the Finite Element Method (FEM). The device is based on the cloaking concept. This is constructed employing a coordinate transformation considering Maxwell’s Equations independence from coordinate system. The frequency selection is obtained due to the frequency dispersion characteristic of metamaterials, and varies over time by tuning its resonance frequency which is a consequence of entropy condition on resonant media. A full device system is simulated in order to analyze the advantage of using such systems in EM wireless communications.
