Lossy Circular Waveguide
In mode analysis and eigenfrequency analysis, the primary goal is often to find a propagation constant or an eigenfrequency. These quantities are often real valued although this is not necessarily the case. If the analysis involves some lossy part, like a nonzero conductivity or an open boundary the eigenvalue is complex. In such situations, the eigenvalue is interpreted as two parts:• The propagation constant or eigenfrequency • The damping in space and time
This tutorial shows how to set up a mode analysis with lossy metallic walls for a waveguide. The attenuation in dB per km is extracted for several modes.
