Abstract

Abstract: The development of an elliptical–cylindrical cavity for microwave thermal processing of materials at high electric field strengths is reported. The design methodology based on numerical modeling is validated by experimental measurements. The system can create high‐power densities in the heated phases, excellent treatment uniformity, and stable operation without degenerated modes or polarization rotation as suffered by other commonly used circular resonator cavities.
