Summary:In this work, the goal is to fabricate and measure a small-scale version of a metamaterial, capable of efficiently shielding the magnetic field from a Wireless Power Transfer (WPT) charging system designed for automotive applications, therefore in the kHz frequency range. The metasurface, which is passive, is configured in a 2D layout, consisting of resonators, or unit-cells, arranged in a 7×7 square matrix: it will be activated through inductive coupling with the nearby WPT system. Current research in this area is limited, predominantly focusing on the use of homogeneous metamaterials for low-frequency magnetic shielding. Nevertheless, studies indicate that inhomogeneous materials exhibit superior shielding effectiveness. Consequently, this work delves into measuring the performance of inhomogeneous metamaterials specifically for future implementation of it as magnetic shielding.
