Abstract

Improving the uniformity of electromagnetic field and temperature in the resonant cavity is a hot issue in microwave heating. In this study, a new method for the design of slot waveguides applied to microwave heating is proposed, which is based on Taylor synthesis method and multi-physics calculations. The initial length, width, and offset between the centerline of the slot are designed by Taylor synthesis method, and the spacing between two slots, including the number of slots, is also determined by Taylor synthesis method. Subsequently, by combining electromagnetic fields, temperature fields, and specific characteristics of the heated object, multi-physics calculations are performed, and the above parameters are further optimized to design the slot waveguides. The results show that the slot waveguides designed by the proposed method produces a more uniform temperature and electromagnetic field distribution than the conventional method.
