摘要

In recent years, the electromagnetic scattering from the coated conductors has been paid more and more attention by many scholars. The parabolic equation (PE) method is firstly utilized to analyze electrically large conductors coated with lossy medium in this paper. The impedance boundary condition is implemented to analyze the lossy medium and the implicit finite difference method of Crank-Nicolson scheme is implemented to solve the parabolic equation. As a result, the computations can be taken in each two-dimensional transverse plane. By this means, both the CPU time and memory requirement are reduced greatly. Numerical results are given to demonstrate the accuracy and efficiency of the proposed method.
