2015) Design and measurement of a W-band Brewster window. IEEE Microwave and Wireless Components Letters, 25 (12). Abstract-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
