This paper presents the design, simulation and technical considerations of terahertz output windows, based on the multilayer type, for THz gyro-TWAs. Such windows can achieve very low reflection levels over a frequency broadband when the thickness of the dielectric layers are properly matched. The optimized window, in this design, was numerically calculated to achieve a passband of over greater than 7% bandwidth with a reflection of less than -30 dB and transmission loss of better than -0.3 dB.
