New glass wafer suitable for waveguide of AR/MR glasses was developed. This wafer has high refractive index, superior transmittance and ultimately high smoothness, which realize highly efficient light propagation. We fabricated eye piece with the wafer and demonstrated it enables AR/MR glasses to display wider and brighter image.
RF-DC conversion circuit is one of the most important components in the wireless power transmission technologies. For realizing highly efficient wireless power transmission, it is necessary to design the RF-DC conversion circuit with high conversion efficiency, and the designing method of the circuit is actively investigating. In this paper, we manufacture the GaN schottky barrier diode for a high...
Space Solar Power System (SSPS) has been proposed to make use of microwave, and it is important to steer the beams toward the receiving system accurately. To control the phases among numerous transmitters with a high degree of accuracy, it is necessary to correct the output phase variations automatically. Therefore we have developed the automatic correction system of the phase variations generated...
Institute for Unmanned Space Experiment Free Flyer, USEF, has been studying Space Solar Power System, SSPS, as future electricity alternative energy source since 1990s. From 2009, USEF started research and development project of Microwave Ground Wireless Power Transmission under a support of Ministry of Economy, Trade and Industry, METI. This project plans to test ground wireless power transmission...
