Abstract：
Eigenfrequencies of high order modes in the axial-symmetric cavities are computed with a vector finite element method. Mathematics models and physics theories are combined in a rational way, which avoids the spurious modes caused by ordinary finite element methods. Using quadratic scalar and vector basis functions, high accuracy of results are available with few meshes. A code named Cafe is presented. It provides a good base for further research of wakefields of the detuned structures in next generation linear collider.
