agursc.sty
agursc-sample.tex
agursc.txt
LaTeX sty file used for publications in AGU Radio Science.
The file agursc-sample.tex shows an example of how to
use the sty file to produce layout ready copy for AGU.
complex.2.0.tar.Z
Complex dense linear solver from:
T. Cwik, R. van de Geijn, and J. Patterson, "Application of Massively Parallel Computation to Integral Equation Models of Electromagnetic Scattering (Invited Paper)," J. Opt. Soc. Am. A, Vol. 11, No. 4, April 1994.
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.
kdps.tar.Z
kdps.txt
by Bengt W Littmann. Mode matching program calculating the
scattering parameters of a waveguide cross-section
jump. See kdps.txt for more info on opening files.
miev.tar.Z
Calculates scattering from homogeneous or conducting sphere for a wide
range of arguments; MIE series solution.
monopole.f
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) of
angle (degrees) and normalized field (deciBels). The program is
set up to output from 0 to 360 degrees in 1 degree increments.
polar_plot.tar.Z
polar_plot.txt
by Louis Wilson. PostScript polar plotting program
powerSmith.zip
Smith Chart program for PCs.
rel_error.f
by Marco Kunze. Calculates the relative error in the infinity-norm in
"Ax" if Ax = b
smith-ps.f
smith-ps.txt
by Louis Wilson. Plots normalized impedance data on a smith chart. Sample input file is
included in monopole.txt. The output is a file
(smith.ps) in Postscript format.
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."
tscht.f
by Marco Kunze. Calculates the Tschebyscheff-Polynomials T of the first
order. The argument of the polynomials is real.
tschu.f
by Marco Kunze. Calculates the Tschebyscheff-Polynomials U of the second
order. The argument of the polynomials is real.
xyfdtd.tar.Z
by Louis Wilson. 2 dimensional Finite-Difference Time Domain demo
program using the Yee algorithm and Mur absorbing boundary conditions.
Uses X-windows to display the wave propagation. The input file contains
all the input parameter definitions with a sample case.
zeros.f
zeros.txt
by Louis Wilson. This subroutine computes the zeros of the Bessel function J or its
derivative J' and stores a table to an array. This array
may be written to a file for later use. It can be used to compute
cylindrical waveguide modes.

GRASP8W, a set of tools
for analysing general reflector antenna systems. The software package
calculates the electromagnetic radiation from systems consisting of
multiple reflectors with several feeds and/or feed arrays using
advanced, state-of-the-art analysis methods. These comprise Physical
Optics, Physical Theory of Diffraction and Uniform Geometrical Theory
of Diffraction. To assist the user in setting up the scattering
geometry as well as in visualising the results, the software package
also includes a graphical interface in the form of pre- and
post-processors. The software, developed by TICRA, is commercial. A
Student Edition, GRASP8W-SE,
is available as freeware for both Windows and Linux platforms.
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.
QuikNec Antenna Software, which generates geometries used in antenna simulations, usable under Windows, from ThinkWireless, Inc. This code is commercial.
Other information and links about NEC, written by Dave Michelson, is also available.
