Indoor Propagation of Diffracted Signals

The incident signals at an indoor receiving antenna in a 2-D room are analyzed. A room with an aperture and walls of standard building materials was considered. An incident plane wave to the room with TE polarization was used. Diffraction for an aperture, multi-reflection into the walls and propagation into the room were contemplated. FDTD, ray tracing, and image methods were applied to obtain the receiving indoor signal
