Simulation-Based Evaluation of Microwave Leakage Mitigation Mechanisms for Process Openings

Microwave heating has found widespread application across various industrial sectors. In recent years, regulatory standards concerning microwave leakage have become increasingly stringent. For continuous processing involving microwave irradiation of objects with considerable size, openings are required to allow material transport. However, these openings pose a potential source of microwave leakage. To address this, leakage suppression must be achieved through an appropriate combination of structural design and material selection. This presentation details the design methodology for such a structure and presents validation results obtained through both experimental measurements and numerical simulations.
