Biological effects of high-power microwave power transfer for electric vehicle
2016 IEEE Wireless Power Transfer Conference (WPTC), 2016The biggest advantage of microwave power charging for electric vehicle (EV) is the capability of charging for a running vehicle. However, the commercial application of microwave charging EV is still difficult because of some issues including technologies and safety.

Experimental Evaluation on RSSI-based Phase Optimization in Microwave Power Transfer
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021In this paper, we present an experimental evaluation of the several phase optimization algorithms for distributed cooperative microwave power transfer. The proposed evaluation uses multiple Tx antennas distributed in a space. When the Tx antennas are in the far field from each other, appropriate phase control can generate constructive interference at ...

Experiments on driving a low-power DC motor by microwave power transfer
2015 IEEE Wireless Power Transfer Conference (WPTC), 2015The input load characteristics of a DC motor vary with input powers. The conversion efficiency of a rectifying circuit is strongly affected by the connected load. Therefore, to efficiently drive a DC motor using microwave power transfer (MPT), it needs to improve the efficiency-load characteristics of the rectifying circuit.

Microwave Power Beaming for Long Range Energy Transfer
8th European Microwave Conference, 1978, 1978Current studies by NASA have identified space solar power as a potential long term viable candidate for efficient energy transfer at orbital ranges using a microwave beam. This paper will describe some of the power-aperture relationships leading to a potential feasible design of a power beaming system.

Resistive power splitter in microwave power standard calibration transfer
Measurement, 1988The problem of accurately calibrating one power meter from another is not trivial, certainly when precise broad-band measurements are required. The main error sources — mismatches — often impair accuracy very seriously and correction methods for these errors are either time-consuming or complicated.

Design of a Circular-Patch Reflectarray for Microwave Power Transfer and Communications in Space
2019 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2019This work presents the design and simulation of holographic reflectarrays made up of circular patches for wireless power transfer (WPT) in the Fresnel region. We simulate efficient focusing at 5.8 GHz for a 1.216m square reflectarray design at a focal distance of 10m.

Design of an RF Power Generator for Directional Radiation in Microwave Power Transfer System
2019 IEEE 13th International Conference on Power Electronics and Drive Systems (PEDS), 2019This paper presents a kind of radio frequency (RF) power generator with ability of directional radiation in microwave power transfer (MPT) system. This power generator uses quadrature modulation which can regulate amplitude and phase as a close loop.
