A finite element method(FEM)with hybrid nodal and edge basis functions for solving non-axisymmetric modes in axisymmetric resonators filled with inhomogeneous media is presented.Spurious modes can be reduced by choosing proper basis functions.Several numerical results are presented to show the validity and the efficiency of proposed method.This method can be widely used in electromagnetic(EM)engineering design.
