ABSTRACT:A hybrid technique for the analysis of horn antennas is described based on a rigorous description of the horn aperture-free space discontinuity. The transition from the feeding waveguide to the

The analysis and design of a cylindrical cavity for microwave heating applications, including the feeding mechanism is proposed in this paper. The cylindrical cavity design aims at the production of a uniform field distribution, avoiding non-uniform heating and thermal runaway. The analysis of the device is based on the Mode Matching Technique. This has been proved to be an efficient and robust technique for the analysis of multiple discontinuities. The feeding structures maybe a circular, rectangular or coaxial waveguide. All quantities involved in the analysis are evaluated analytically achieving a fast and accurate method.
