Abstract
A novel design of notch filter was proposed and tested. Waveguide filter consists of a prismatic cavity coupled to waveguide by a slot and a frequency tuning plunger. We intend to apply this filter for measuring the output radiation of Ka-band gyrotron operating in regime of rogue wave generation and for microwave plasma diagnostics. X-band and Ka-band prototypes of the filter were manufactured and their characteristics were measured. Four-cavity filter was designed and its characteristics were numerically simulated.
