A Jerusalem Electromagnetic Compatibility Coat for a Cubic Wireless Charging Container

Wireless charging technology is an emerging field that utilizes electromagnetic fields or radio-frequency signals to transmit power through the air or other mediums. However, the high-power output of wireless charging systems may lead to electromagnetic interference and noise, affecting the performance of nearby electronic devices and causing a degradation in the overall wireless system performance. This paper introduces a cubic wireless charging container featuring a Jerusalem electromagnetic compatibility (EMC) coat. To reduce the physical dimensions of the frequency-selective surface (FSS), an improved Jerusalem FSS configuration is designed. Simulation results indicate that the proposed Jerusalem EMC Coat effectively prevents electromagnetic radiation leakage from the cubic wireless charging container when operating at 13.56 MHz.
