Abstract

In this paper, a fast algorithm is presented to compute the electromagnetic fields of a thin wire current source inside lossy ground. The modified image method is used to evaluate the Sommerfeld integrals, and the fast multipole method (FMM) is utilized for solving the governing electric field integral equation (EFIE). The validation of the proposed algorithm is performed by comparing the results with that of using method of moment (MoM). The numerical example shows the flexibility, efficiency and accuracy of this algorithm.

Key words： modified image theory; lossy ground; fast multipole method (FMM)
