| Abstract: | This article introduces one method for optimising a microwave oven using microwave CAD technology. The precision model of a microwave oven cavity is created by high-frequency electromagnetic simulation software, and the electric characteristic parameter of the materials are set in the cavity so the simulation model is very close to a practical oven cavity. A new experimental set-up consisting of a multimode microwave cavity, a dielectric parametric test system, a vector network analyser, a microwave power source (magnetron) and a thermo-graphic camera has been built and tested. Comparing the simulation result with the experimental measures (phase polar and power loss), their total properties are consistent. It is proved that the method presented here is practical and useful. So optimisation of the oven design is easily done by modifying the cavity model. |
