Abstract (in Japanese) (See Japanese page) 
(in English) In research on conventional waveguide power transmission using a sheet-like waveguide with 2.4 GHz, a transmission range was limited to tabletop size. Our goal is extending the transmission range to several tens of meters by modifying the operating frequency, surface conductor pattern, and coupler size. This paper shows that a design method of a long-distance waveguide power transmission system using a sheet-like waveguide. Simulated result shows that the practical transmission efficiency is achieved with 6.78 MHz while maintaining the characteristics of the conventional sheet such as the simplicity of the seat structure, the ease of installation, and the suppression of electromagnetic field leakage into space. Simulations using a simulated human body model shows that a power of 3 kW or more could be supplied to a load 20 m away from the power supply while complying with safety standards.
