Analysis of Electromagnetic Scattering from a PEC Sphere by the 3D Point Matching Method - Prediction for Computational Accuracy of the Radar Cross Section

摘要

The point matching method can analyze electromagnetic scattering problems with a high degree of accuracy. Recently, we have proposed a prediction method for computational accuracy of two dimensional problems. In this paper, we extend the idea to three dimensional problems and investigate computational accuracy of the electromagnetic scattering from PEC and homogeneous dielectric spheres. Compared with the analytical Mie series solutions, our prediction method for the three dimensional problems is verified.
