In this paper, shooting and bouncing ray — physical optics / physical theory of diffraction (SBR-PO/PTD) hybrid method is studied to investigate the backward scattering from three-dimensional (3D) electrically large target. Shadowing effects, multiple bounce, and diffraction by edges are considered in this scattering model. Time-consuming is greatly reduces compared with the numerical methods such...
In this letter, a novel method is proposed to assess the simulation of scattered fields from electrically large complex metallic objects. The basic idea is to employ Open Graphics Library (OpenGL) to accelerate paths tracing for geometrical optics (GO) and physical optics (PO) hybrid method. The procedure of OpenGL-based paths tracing is divided into two steps, which are shadow faces removal and reflected...
