Abstract :
A simple model for predicting the characteristic energy decay time of wireless RF emissions in confined, reflective spaces is presented. Based on this cavity decay time, accurate estimates of room quality factor, diffuse (multi-path) insertion loss, and average electric field components are possible. Spaces of interest for model applications include aircraft cabins, below-deck compartments in ships, automobile interiors and metallic building or room enclosures. Decay time predictions are shown to be in excellent agreement with measured data from two different reverberant spaces over the 1-14 GHz frequency range.
