Improvement of Microwave Heating Performance via a New Combination Method

Microwave heating has attracted extensive attention of the public because of its convenience and high efficiency. However, it usually leads to non-uniform temperatures. In this paper, a new combination method of rotating turntable and selected frequencies is proposed to improve the heating performance. The Finite Element Method (FEM) is used to simulate the heating process and assess the performance. The results show that the proposed method can improve heating uniformity and heating efficiency effectively.
