The Equivalent Plane Model (EPM) and Phase Correction Algorithm (PCA) that are based on Transmission Line Theory (TLT) are proposed to satisfy the resource and efficiency requirements of ElectroMagnetic (EM) scattering analysis of large and complex multilayered dielectric targets. The proposed method accurately predicts the EM scattering characteristics of reference targets. To simplify the analysis, the multilayered dielectric slab structure is considered planar. On the basis of the TLT, the reflection and transmission coefficients of the plane are determined by using network analysis methods typically adopted in circuit analysis. Moreover, the reflection and transmission phases are corrected by considering the thickness of the multilayered dielectric slab and the direction of incidence and observation. Simulation results verify the applicability of the proposed method.
