The transmission‐line matrix method is a time‐domain numerical method for solving wave problems. This paper describes how a minor change in the computer program for loss‐free dielectrics extends the method to include dielectric losses. Results are given in terms of the wave impedance of a waveguide with losses, and also in terms of power decay due to losses in the dielectric of a resonant cavity.
