Full-wave study of electromagnetic susceptibility inside a complex platform using domain decomposition methods

Summary form only given. The accurate simulation of high-power microwave (HPM) with very short rise time and intense energy pulse and the field penetration into a multi-scale and complex system are of vital importance. When the pulse hits the platform, field penetrates inside through apertures by front door and back door coupling. If the incident pulse has strong frequency spectrum component at the resonant frequency of the cavity structure, then the field intensity inside the platform will accumulate after a few pulse trains and couple through the cables to electronics.
