Outline of Final Research Achievements

A wireless power transmission system, which works in the range of frequencies of 17.5GHz to 19.0GHz, is designed by using methods of quasi-optics and which characteristics are experimentally measured. The system consists of two parabolic antennae of 400mm in diameter and the distance between two parabolic antennae is 1500mm. The power transmission efficiency of the system is 40% to 45%. Small distance changes do not influence the power transmission efficiency.
A passive device made of two-dimensional transmission plane, which characteristics is depend on the boundary condition of the two-dimensional transmission plane, is proposed, designed and evaluated experimentally.
