    Abstract

    This paper presents the design and simulation results of an output coupler for a gyro-amplifier operating at THz frequencies. The combination of a smoothly profiled horn and multilayer microwave window allow for the almost total conversion of the TE11 mode to the Gaussian-like HE11 mode while forming a vacuum tight seal with very low reflections. This assembly operates over the 360-384 GHz frequency range.
