EM Simulation and Mechanism Analysis of Dielectric Coated Complex Target Based on MoM-PO Method

Based on the impedance boundary condition (IBC), the paper firstly proposes a MoM-PO hybrid algorithm for high-precision and rapid prediction of electromagnetic (EM) scattering of dielectric-coated complex targets. Aiming at the difficult problems of scattering sources and mechanism analysis of complex targets, a set of scattering source analysis methods based on component decomposition is proposed. The article takes the B-2 Ghost strategic bomber as an example. The simulation results are in good agreement with the exact solution. The in-depth analysis of the scattering mechanism of the target under the three conditions of ideal conductivity, overall dielectric coating and partial dielectric coating verifies the engineering application value of the research content of the article.
