Implementing OSMEI on 3‐D arbitrary conducting objects

A sparse technique for the dense matrix of the method of moments (MoM) is implemented to the electromagnetic scattering of a 3-D arbitrary conducting object for the first time. The numerical examples for the plane-wave scattering of a conducting sphere with 0.2 and 0.4λ show that the surface current densities of OSMEI and MoM agree well. © 2001 John Wiley & Sons, Inc.
