Abstract
Based on the second kind of Green’s identity, a boundary integral equation for arbitrary cross-section waveguide is transformed to a system of linear homogeneous algebraic equations by means of expansion of boundary bases and by using the eigen functions of a fictitious regular boundary as weighting functions, which corresponds to less algebraic equations than BEM and simpler coefficients than the modified BEM. The numerical results for some typical metallic waveguides are given by using the method of eigen-weighted boundary integral equation, and they are accurate enough with fast convergence.
