Abstract

In this paper, we present an efficient meshing scheme for physical optics calculation of electromagnetic scattering from bodies of revolution. Piecewise linear approximation is used to represent the generatrix and circular perimeter of the body's cross section. This results in quadrilateral meshes and enables the application of multilevel search algorithms for efficient determination of the illuminated portion of the surface. Besides, the physical optics surface integral is reduced to a closed form expression using the Gordon's method. Simulation results conrm the proper accuracy and efficiency of the presented algorithm.
