An EM Scattering Prediction Method Based On Reflection Coefficient Loading For Structures With Medium

Aiming at the electrically large-scale conductor composite structure where dielectric materials are applied locally on the surface, based on the equivalent source modeling of the reflected field and the equivalent principle of the dielectric domain, a correlation model between the reflection coefficient in the wide-angle domain and the scattered field is proposed, which is realized by loading the vector reflection coefficient of the composite material structure. The high-frequency approximate prediction of electromagnetic scattering characteristics supports solving the contradiction between the electromagnetic simulation accuracy and solution scale of complex conductor structures containing dielectric materials. The accuracy and feasibility of the prediction method in this paper are verified by comparison with the calculation results of the full-wave numerical method.
