In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and imaginary parts have separate interpretations: * The real part is the propagation constant * The imaginary part is the attenuation constant, measuring the damping in space

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.
