In this paper we analyze the eigenvalue problems of resonant cavities using higher-order hierarchical vector basis functions based on tetrahedral finite elements.The numerical results of several examples show that using the higher-order basis functions can reduce unknowns by larger discretization size to obtain the same accuracy with the lower-order basis functions,and the numerical solution can approach the analytical solution more quickly with mesh refinement.

Key words: finite elements;higher-order basis functions;cavities;eigenvalue
