Abstract

This paper presents the design of a TE10-to-TE61 mode coupler for a 372 GHz gyrotron travelling wave amplifier. The optimized coupler was able to achieve an -1 dB transmission over the frequency band of 360-384 GHz. The transmission decreases by 1.2 dB when the copper conductivity of 0.5E7 S/m was used in the simulation. The designed coupler was scaled to W-band for manufacture and measurement. The measured transmission and phase response confirmed the mode coupling between the input TE10 mode and the desired TE61 mode.
