The variational method for analyzing the loading cavity with complex plate load is given, and the boundary conditions satisfied by the sub-regions are obtained by the field matching of each sub-region in combination with the field matching technique. For the boundary where the tangential magnetic field is zero, The optimal boundary conditions are obtained on the basis of minimizing the area fraction of the square of the electric field difference.The method and procedure for the analysis and synthesis of the cavity using the plate load radius as the intermediate are given.The results show that the relative Accurate resonant frequency value.
