Abstract

In order to evaluate the heated process of the target, S parameter, and initial design of cavity size in the furnaces for dielectric heating such as microwave oven, the coupled analysis of electromagnetic wave and heat conduction (EM-HC coupled analysis) is a useful tool for practical design. In this paper, valuable EM-HC coupled analysis method with rotational motion of heated target such as turntable and temperature-dependent complex permittivity by using edge-based finite element method is proposed. As a result of useful investigation of the proposed method, the effectiveness in tracing the detailed temperature rise of dielectric target is demonstrated.
