Abstract

We present the mathematical analysis, based on an eigenfunction expansion, and the main steps of the corresponding numerical code developed to calculate the dispersion relation and the field distributions for all kind of waves, which can propagate in a nonperiodic circumferentially corrugated circular waveguide with losses. The code offers fast computations with accuracy, which can be chosen by the user. Numerical results are given for several geometries and comparison with already established codes is made.
