Analysis of EM scattering characteristics from 2D electrically large objects using characteristic basis function method

Characteristic basis function method (CBFM) is a novel approach for the efficient solution of electromagnetic scattering problems. In this paper, CBFM combined with the domain decomposition technique is used to calculate the radar cross sections from 2D electrically large conducting cylinder and dielectric cylinder. It is shown that the numerical results presented in this paper are in good agreement with that achieved by the traditional method of moments, while the computational efficiency is improved greatly.
