A Brewster window integrated into a corrugated waveguide was designed, manufactured and studied for a W-band gyrotron traveling wave amplifier. A corrugated waveguide intended to guide a quasi-plane wave (HE11) through the window, was numerically optimized and verified by measurement using a Vector Network Analyzer. The Brewster window was measured to have a reflection lower than -22 dB for the TE11 mode over the frequency range of 85 - 101 GHz.
