| Abstract: | The concrete procedure using finite-element method to solve the eigenvalue problem of waveguides filled with inhomogeneous dielectrics is discussed. The relative formula and programs are given. For an example, the field structure analysis and calculation of the dispersion feature for dominant mode of the dielectric slab loaded rectangular waveguide have been completed. The rather consistent results with analytical solution are obtained and the reliability of the programs is verified. |
