Abstract
In this letter, we review the calculation of the propagation constants in a circular lossy waveguide. We highlighted some improvements in order to find the propagation constants of the guided modes. We present a new characteristic equation that simplifies the application of the winding number technique described in previous publications, and also we discussed some numerical criteria for the application of this technique.
