The programs "fourd.f90 and fourdcu.f90 implement the scattering equations described in J. H. Richmond, "Scattering by a Dielectric Cylinder of Arbitrary Cross Section Shape." IEEE Trans. on Antennas and Propagation, vol AP-13, pp 334-341, May 1965. The output of these programs, out.dat, is a field strength around the dielectric cylinder as a function of angle.
A similar program was used for parameter studies for the design of the AGM-129 Advanced Cruise Missile. See: http://www.fas.org/nuke/guide/usa/bomber/acm.htm and take a close at the picture that shows a number of missiles in the factory.
These programs take two input files, wing.dat and source.dat
The file wing.dat is generated by running the program airfoil.py. This generates a description of a wing. Airfoil.py can be run without any input parameters but it can take the number of cells in the decomposition.
The file source.dat contains three lines. The first gives the method used to solve the linear system. It is one of the following:
*** The cula option is only valid for fourdcu.f90 ***
The second line of source.dat gives the wavelength of the radar in meters.
The third line gives the width of the radar beam in +/- degrees.
The programs mkl.f, mkl.c, nrf.f90, and nrfcuda.f90 are some other test programs.
The makefile contains options for several versions.
The makefile also creates the wing.dat file if it does not exist.
As of Jan 11, 2010 the Intel compilers are not installed on cuda1. These programs can be compiled on RA and moved to cuda1. The Portland Group compilers are available on cuda1.
