Single-Layer Single-Polarization Rectifying Surface for Microwave Wireless Power Transfer
2022 IEEE 5th International Conference on Electronic Information and Communication Technology (ICEICT), 2022In this paper, a single-layer single-polarization rectifying surface for microwave wireless power transfer is proposed. The proposed periodic rectifying surface cell is composed of integrated receiving metal structure and Schottky diode. Firstly, the diode's equivalent impedance is obtained by simulation.

Microwave-band wireless power transfer system using ceramic dielectric resonators
2013 IEEE Wireless Power Transfer (WPT), 2013In the conventional resonator-coupled WPT system, coil resonators made of copper wire are usually used. So, unloaded Q of coil resonator is a few hundred to one thousand due to metal conductivity. There is a limit for transmission distance due to the loss caused by low unloaded Q of the coil resonator.

Gated-Anode GaN HEMT Based Diode for Microwave Wireless Power Transfer
2020 IEEE Wireless Power Transfer Conference (WPTC), 2020We have introduced a gated-anode diode using a normally-off AlGaN/GaN HEMT. For precise control of turn-on voltage without spoiling an advantage of mono-layer controllability in epitaxial growth, we have selectively dry-etched a GaN cap layer to expose AlGaN Schottky layer to a surface.
