Abstract: In this paper the finite-element analysis method of waveguide eigenvalue problem is briefly discussed. A standard program using finite-element method to solve waveguide eigenvalue problems is presented. With this program, it is possible to calculate the eigenvalues and eigenfunctions for a group of waveguides consisting of lines and circular arcs. The calculations of eigenvalue problems for more than ten different structure waveguides verify the reliability of the program. -
