cyl.f
Calculates
exact series solution for RCS of an infinite cylinder.
dte.f
and dbess.f
(required by dte.f)"... calculates the exact solution for the near fields in and around a 2-D cylinder. This is for the 2-D TE case. ... The code is for "near" fields and due to the limits on the number of HANKLE functions, it will not work if a large area relative to the size of the cylinder is chosen. The code could be modified to perform far field approximations to eliminate this problem. ... I also have coding for the TM case but it has not been thoroughly checked out. I provide it on an individual case with that understanding. I can be contacted at: klysiak@swri.edu".
grating.f
grating.txt
by
Tom Cwik. Computes the exact reflection and transmission coefficients for a
p.e.c. strip grating. For this exact solution, the strip width to cell size
ratio is 0.5 and the excitation is normally incident. The solution is due to
Weinstein using the factorization method.

monopole.txt
by
Louis Wilson. Calculates the fields of a monopole on a circular ground plane
using the Uniform Theory of Diffraction using a formulation by Dr. Robert
Kouyomjian. Operation is interactive and the output is a file (monopole.dat)

stack.for
by
Barry Chambers.
"... Calculates and plots the variation with frequency of the reflection and transmission coefficients for a stack of lossy dielectric layers with optional interface impedances. The incident wave may be at any angle and have either parallel or perpendicular polarisation. The software is based on theory given in the book: "Radar Cross-Section" by Knott, Schaeffer and Tuley (Artech House 1993) and can be used to design multi-layer windows or radar absorbers."

Equipotential Surfaces and E
Lines, 3D Software for calculation and visualization of equipotential
surfaces and electric field lines with topographic view and deals with many
kinds of charges (dotive, linear, page..sphere, di electric). The program runs
on PC computers with Win95 compatible operating systems, the downloaded
version will work will all features for 30 times, then the user will decide to
buy it or not.
Two unofficial web sites containing the non-commercial software exist:NECSee, a visualization tool for antennas, which operates on NEC output files. One version is free, the enhanced version is commercial.
NEC-Win Pro and NEC-Win Basic, PC-based GUIs for the NEC code, from Nittany Scientific. These codes are commercial.

SuperNec 1.53, is a hybrid Method of Moment (MoM) / Unified Theory of Diffraction (UTD) antenna analysis program. The Matlab graphical interface that sets this product apart from the rest was developed by Dr Nitch. SuperNEC 1.53 incorporates ready made antenna assemblies,support for dielectric-coated wires and context sensitive help. SuperNEC 1.53 is free for non-commercial use to everyone who has Matlab 5.2 or better.
