Abstract

This paper examines the possibility of 30 W (more exactly 34 W) power transmission through 2D waveguide (2DW) sheet satisfying electromagnetic compatibility (EMC) requirements. The system enables wireless charging to ubiquitous robots for generating a flexible communication network. As the riskiest case in general environments, we suppose a resonant metal plate is put on a 2DW sheet. The radiated power density from any metal plates should be less than the guideline provided by International Commission on Non-Ionizing Radiation Protection (ICNIRP). Satisfying this condition, we achieve safe 30-W transmissions by thickening the surface insulator layer of 2DW to 5 cm and enlarging the coupler size to 30 by 43 cm.
