| A finite element method(FEM) with hybrid nodal and edge basis functio
ns for solving nonaxisymmetric modes in axisymmetric resonators filled with in
homogeneous media is presented. Spurious modes can be reduced by choosing proper
basis functions. Several numerical results are presented to show the validity a
nd the efficiency of proposed method.This method can be widely used in electroma
gnetic(EM) engineering design. |
