Numerical-Analytical Computation Method for Cutoff Wavenumbers of Waveguides with Complicated Cross-Section
RESUMO
The paper considers a new numerical-analytical technique for computing the cutoff wavenumbers of hollow regular waveguides having a continuous curvature of the cross-section contour or a curvature with a first kind singularity. The method is based on the boundary integral equations of the potential theory and a special parameterization of the cross-section contour. The details of the numerical implementation are illustrated by a circular waveguide and a rectangular one with rounded corners. The perturbation theory is employed to derive the analytical formulas for the cutoff wavenumbers of waveguides with piecewise linear boundaries and rounded corners. The application range of these formulas is determined.
