A hybrid technique which combines the integral equation (IE) method and the multiple image theory (MIT) is presented for modeling the electromagnetic wave propagation in a closed environment like aircraft cabins. The IE method with a method of moments (MoM) procedure is employed for analyzing the transmitting antenna. The obtained current on each basis function is acting as a source, and all its multiple images with reference to the wall planes for multiple reflections up to a given order are found out. The multiple images are then used to track the multiple reflected ray paths and further used for the calculation of reflected fields. Since no unknowns are used on the cabin walls, the hybrid technique is well suited for electrically large cabin problems. Numerical examples are presented to demonstrate the accuracy and capability of the presented technique.
