A high-power RF-to-DC rectifier applied to wireless power transfer (WPT) with ultra-wide input power dynamic range is proposed in this paper. A GaN (gallium nitride) HEMT (high electron mobility ...

To break limitation in the bandwidth of traditional SB-TWTs at high power of its operation, an innovative Double-Ridge Staggered Vane (DRSV) Structure is proposed and verified as an effective solution ...
