Abstract

A quasi-optical mode converter in the form of a corrugated horn has been constructed for a W-band gyrotron traveling wave amplifier (gyro-TWA). The prototype was designed and optimized through analytical and numerical simulations. The horn converts a cylindrical TE 11 mode into a free-space TEM 00 mode in a frequency band of 90 GHz to 100 GHz. The optimized simulation predicts a return loss better than -35 dB and a Gaussian coupling efficiency of 97.8% and the measured prototype demonstrates a close agreement with these figures.
