Design and Analysis of 25 kW(CW) Millimeter Wave Source with External Waveguide Mode Converters for Advance Material Heating/Processing

The design of millimeter wave source of 28 GHz frequency with 25 kW RF output power is discussed here. Also the design of waveguide mode converters (rippled wall, serpentine and corrugated) to convert the operating mode into Gaussian mode is discussed. The design of the millimeter wave source and transmission system is performed considering its potential applications in the precision heating and high-quality processing of the different materials of low loss factor. The commercial as well as indigenously developed design codes of beam-wave interaction and beam trajectory analysis are implemented in the design and analysis of the device.
