Ray-Enhanced Scheme for High-Frequency Scattering Analysis of Complex Targets

This paper introduces a ray-enhanced numerical scheme that effectively tackles the challenges associated with complex target scattering analysis in the high-frequency region. Through the integration of ray information with the classical finite element method, our approach achieves a remarkable reduction in the mesh size for discretization compared with classical numerical methods. The performance of the solver is evaluated by simulating a typical plane target, showcasing the stability and efficiency of the proposed method.
