Efficient and fast Gaussian beam‐tracking approach for indoor‐propagation modeling

A Gaussian beam‐tracking technique is proposed for physical indoor‐propagation modeling. Its efficiency stems from the collective treatment of rays, which is realized by using Gaussian beams to propagate fields. The formulation of this method is outlined, the computation‐time efficiency is discussed, and the simulation results are compared to those obtained using a commercial ray‐tracing software (X‐Siradif®). © 2005 Wiley Periodicals, Inc.
