Based on electromagnetic topology and statistical concepts, Power Balance (PWB) method is used to estimate the magnitude of electromagnetic energy in electrically large system under high-frequency interference. The comparison of results obtained from PWB method and full-wave analysis method shows that PWB method can indeed provide effective data that meets certain accuracy requirement. This article uses PWB method to evaluate mean quality factor and the shielding effectivenes of the the Boeing 747-8.Comparison with the full-wave analysis method proves that this method has advantage of convenient and fast and has wide range of usage scenario.
