pp: 801-807Analyses of Multimode Forming Process in a Microwave-heating CavityJirun Luo doi:10.2529/PIERS060819040945 Downloads: 993 Abstract:A definition of electromagnetic mode, based on its propagation direction and the distance from the cavity axis with cutting angle θB and caustic radius Rc, is given and used to describe multimode forming process in a circular cylindrical cavity for explaining its effect on the quality of field homogeneity. And the effect of polygonal cylindrical cavity as well as the properties, size and shape of the material sample processed in the cavity on multimode forming process is also discussed.References:1.
