NAFDTD - A Near-field Finite Difference Time Domain Solver

Abstract

This report describes NAFDTD, a near-field finite difference time domain software package developed at the U.S. Army Research Laboratory (ARL). This program is based on the finite difference time domain (FDTD) method and is related to the AFDTD software. Unlike AFDTD, which is designed for radar signature analysis in the far field, NAFDTD is an electromagnetic solver for near field geometries. The differences between the two configurations receive particular attention, followed by a presentation of the numerical issues specific to the near field case. The report contains a user's manual for the NAFDTD program, as well as the companion SOURCERECEIVER utility software. Several numerical examples provide software validation.
