| Abstract: | Analyzing the electromagnetic scattering of electrically large targets with complex coatings presents significant computational challenges. This study proposes a highly efficient hybrid acceleration method within the Electric Field Integral Equation (EFIE) framework, combining the Thin Dielectric Sheet (TDS) approximation, Characteristic Mode Analysis (CMA), and Adaptive Cross Approximation (ACA). First, a generalized TDS formulation maps dual-layer equivalent currents onto a single-surface model, substantially reducing the number of initial unknowns while preserving physical consistency. Next, domain decomposition and CMA are used to construct a reduced-order matrix, enabling a direct, non-iterative solution that fundamentally bypasses the traditional convergence bottlenecks. Finally, the ACA compresses well-separated far-field interactions to further minimize the computational and memory costs. Comprehensive numerical experiments calculating the radar cross section (RCS) of electrically large coated targets demonstrate that the proposed hybrid scheme offers superior accuracy and drastically reduces matrix storage and computation time compared to conventional full-wave direct solvers and traditional TDS-EFIE (electric and magnetic) formulations.
