Composite electromagnetic field estimation method based on element field decomposition and superposition

Abstract

Aiming at the shortcomings of the existing composite electromagnetic field calculation method, the paper puts forward a kind of composite field estimate method based on Element filed decomposition-superposition. Equivalent modeling was carried out on the antenna radiator and its platform use the way of decomposition - superposition. Different features model according to the different electromagnetic calculation method. And then, using the method, it forecast the electromagnetic fields between multiple platforms, and designs the process to predict. It meets the requirement of test electromagnetic environment (EME) prediction for multi-platform. It makes up for the deficiency of the existing electromagnetic environment forecast methods, and is conducive to solve the multiple electrically large platform composite field calculation problems.
