A formulation that allows one to describe scattering from objects in a waveguide has been developed. The method is based on coupling the free-field T-matrix to a waveguide using the normal mode code SWAMP and the T-matrix codes developed at NRL. This formulation allows for the rapid reproduction of solutions and allows one to replicate pulse scattering from resonating objects in a waveguide. Animations of signals scattering from resonating objects is presented. The results are shown to enhance insight into the physics of such scattering processes.
