Popis: | An accurate analysis of the perturbation methods of propagation constants and attenuation coefficients of TE and TM modes in an asymmetric metal/dielectric/dielectric layer structure and four-layer metal-clad waveguides is presented. Simple formulas are deduced, and numerical results and illustrations are given for several guide configurations. The results are in good agreement with exact solutions in the method of solving the eigenvalue equation in the complex plane. Approximate methods and formulas for analyzing metal-clad waveguides with buffer layers are also given. |
