RECTANGULAR AND CIRCULAR WAVEGUIDE FUNCTION SCATTERING PACKAGE

Accurate computer modeling of passive circular or rectangular waveguide
components is often required during the design phase for optimizing
frequency response and/or determining the tolerance required on components
in order to meet radio frequency specifications. RWGSCAT/CWGSCAT is
capable of modeling both types of waveguide components. The Scattering
Matrix Program for Circular Waveguide Junctions, CWGSCAT, computes the
scattering matrix for a circular waveguide. This includes a dual mode horn
and certain types of corrugated horns. RWGSCAT, Rectangular WaveGuide
junction SCATtering program, solves for the scattering properties of a
rectangular waveguide device, such as a smooth or corrugated rectangular
horn, step transformer, or filter. RWGSCAT and CWGSCAT are also available
separately.

RWGSCAT and CWGSCAT are written in FORTRAN 77 for IBM PC series and
compatible computers running MS-DOS. Sample MS-DOS executables and sample
input data files are provided on the distribution media. The standard
distribution medium for this program is a set of two 5.25 inch 360K MS-DOS
format diskettes. An electronic copy of the documentation is included on
the distribution medium in LaTEX format. RWGSCAT was developed in 1993.
CWGSCAT was developed in 1987, and this version was released in 1991.
