An efficient hybrid simulation technique for modeling the electromagnetic field propagation in a closed environment

This paper presents an advanced hybrid simulation technique to model the electromagnetic filed interactions between multi-transmitters and receivers in a complex closed environment; in which the method of moments/circuit method is used to accurately simulate the transceiver, and the longdistance electromagnetic field interaction is efficiently calculated by using the ray tracing technique based on the uniform theory of diffraction. The seamless combination between the circuit, numerical, and asymptotic approaches is the key to get accurate simulation results. Several numerical examples are presented to demonstrate the efficiency of the proposed hybrid technique.
