Abstract

The critical element of a microwave heating system is the resonator, which affects the effective heating of the material to be heated. It is based on the creation of an effective electric field on the material. In order to create a homogeneous and strong electric field in the entire volume of the material to be heated, it is necessary to design a resonator of the correct dimensions. In this study, a model is derived in which the required resonator dimensions for a microwave heating system with a specific resonance frequency can be calculated analytically. The design of a rectangular microwave resonator that resonates at 2.45 GHz is given purely analytically using a derived model. The extracted analytical model is validated by simulation results for two different modes.
