The paper proposed a new method to synthesis circular aperture mm-wave antennas with contoured beam wave in near-field. With derivation on the near-field integral calculus formula of circular aperture antennas, we provided a novel algorithm to transform aperture distribution to axis distribution back and forth using fast Fourier transform(FFT) technology. Referring to the Phase-Only method widely...
The design of a W-band second harmonic gyrotron based on a 1.8 T continuous operation solenoid is presented. A compact triode MIG is designed to generate gyrating electron beam. The gyrotron operates at the TE0,2 mode with a conventional cylindrical cavity. And we designed a high efficiency quasi-optical mode converter with a dimpled wall laucher, the mode conversion efficiency is 97% and the Gaussian...
