The problem of spherical resonator for electromagnetic wave propagation is one of the hot topics; in this paper, we give spherical coordinate transformation and solution of Helmholtz equation, through spherical Bessel function and spherical Neumann function to analysis mode in spherical resonators. Finally, the distribution of electromagnetic wave in spherical resonator is given by numerical example.
