Design and Comparison of Waveguide Windows

The waveguide Windows used in most of the high power microwave Tubes are of different types, namely the rectangular single block window, the multilayer window and the thin disc pillbox window. In this paper, the design of all the three types of windows is carried out in the X-band frequency. The design of the single block window has been carried out with inductive, capacitive and resonant type of irises to find their suitability for window applications. The results obtained from the equivalent circuit have been compared with that of results from the Electromagnetic software HFSS and presented for all the RF windows.
