Abstract

We present a software package INDOOR-GBS (Gaussian Beam Summation) designed to simulate indoor electromagnetic field propagation in the ultra wideband (UWB) regime. The package is based on the GBS method where the field of the transmitting antenna is expanded into a superposition of GBs that emerge from the source in a discrete set of directions. Thereafter the beams are traced in the configuration through multiple reflections and transmissions at the walls/ceilings/floors and the field is calculated by summing the contributions of the beams that pass near the zone of interest. The algorithm consists mainly of two phases: a processing phase where the beams are traced through the medium, and a post-processing phase where the field and the channel parameters are calculated for the given source and receiver antennas. The processing phase utilizes a dyadic electromagnetic formulation so that the antennas' properties are used only in the post-processing phase, thus facilitating efficient post-processing calculations for antenna and channel optimization. The algorithm also employs a particular set of isodiffracting GBs (ID-GB), whose propagation characteristics are frequency independent and lead to efficient UWB calculations.
