Modeling and Simulation of Multi-source Microwave Heating Cavity

Microwave heating technology is a new heating technology which developed rapidly in recent years. Mastering electromagnetic distribution of the cavity is a key factor that can make good use of the technology. This paper introduces the method of using the finite difference time domain method (FDTD) to solve the cavity electromagnetic distribution based on Maxwell's equations, and derives the corresponding electric field differential equations. By using software CST, we get the influencing factor such as different angle and distance between the multiple source feed, the load on electromagnetic distribution of multi-source microwave heating cavity. According to the simulation of the electromagnetic distribution of cavity and S parameter, analyzes these factors impact on the distribution of the cavity. In the design and application of multi-source microwave heating cavity, the factors on the cavity electromagnetic distribution should be taken into full consideration.
