| Abstract: | A combination of the boundary-element method and analytical method is used for analysis of scattering character in a symmetric planar discontinuities dielectric waveguide in this paper.The boundary-element approach is used for the interior region enclosing the waveguide discontinuities, while the analytical approach is utilized for the fields on boundary which connect uniform waveguide to discontinuities . To show the validity of this approach, a computer program is designed and two cases are calculated, the results agree well with the reference data. |
