On Simulating the Radio Signal Propagation in the Reverberation Chamber with the Ray Launching Method
Progress In Electromagnetics Research B, Vol. 27, 83-99, 2011
The modeling of the reverberation chamber with the use of deterministic techniques, one of which is the Ray Launching (RL) method, requires a careful tuning with measurements. A few factors that most severely influence the simulation results are: the minimum number of stirrer rotations to produce representative outcomes, the number of reflections of each traced ray and, finally, the size of the receive probe and the wall reflection loss. In the course of investigations it was demonstrated that these factors have a different, and in some instances --- even opposite, impact on the simulated results in the electromagnetic (EM) power domain and in the time domain (the time delay spread). A simple procedure consisting of a few steps has been proposed for tuning deterministic RL models to the measured data.
