One method of calculating the resonant frequency of cylindrical dielectric resonant with holes is introduced. The method is based on the solution of eigenvalue of the Maxwell equation, and the resonant frequency of cylindrical dielectric resonant with holes is solved by applying the PDE tool box in the Matlab. Compared to the measurement results of the PNA, the error of the method is not more than 0.4%. The numerical method can be programmed by Matlab, and then can be applied conveniently in the test software VEE of the PNA. Thus, the complementary advantages of the method are very beneficial for the design of the resonant frequency of cylindrical dielectric resonant with holes and the deformation cylindrical dielectric resonant, and also can be used for solving many other problems, such as online automatic measurement of the resonant frequency of cylindrical dielectric resonant with holes and the deformation cylindrical dielectric resonant.
