A new approach,the multipole theory(MT) method,is briefly described for analysis of waveguide eigenvalue problems.The essential concept is to represent the solution of the waveguide partial differential equation by the generalized MT formula of 2 D Helmholtz equation.The applied rules and the procedure of the MT method are also introduced.By calculating and analyzing some engineering problems,it is shown that the MT method is an effective approach for analysis of waveguide eigenvalue problems.
