Abstract

Two numerical techniques are applied to boundary element analysis of axisymmetric modes of a cylindrical resonant cavity. One of the techniques is based on a novel expression for the fundamental solution of the axisymmetric Helmholtz equation with double exponential formulas. The other is an integral equation method in which the fundamental solution of the Laplace equation is used by considering the axisymmetric Helmholtz equation as the axisymmetric Laplace equation with an inhomogeneous term. Axisymmetric modes of a cyclindrical resonant cavity are analyzed by these techniques, and the resonant wave numbers are obtained with high accuracy. These results show that the axisymmetric resonant cavities can be analyzed by the boundary element method
