atlc(1) This is the main finite-difference calculation routine.coax(1) Computes impedance of standard coax or eccentric coax. See
also dualcoax(1)create_bmp_for_circ_in_circ(1) For a circular conductor inside a circular conductor.create_bmp_for_circ_in_rect(1) For a circular conductor inside a rectangular onecreate_bmp_for_rect_in_rect(1) For quickly generating bitmaps of rectangular conductors inside rectangular conductors. create_bmp_for_rect_cen_in_rect(1) For quickly generating bitmaps of rectangular conductors placed centrally inside rectangular conductors.create_bmp_for_rect_cen_in_rect_coupler(1) For quickly generating bitmaps of a coupler with think conductors rectangular conductors placed centrally inside rectangular conductors.create_bmp_for_rect_in_circ(1) Currently the programme has not been finishedcreate_bmp_for_symmetrical_stripline(1) For quickly generating bitmaps of thin conductor between two wide groundplanes. Since exact analytical results exist, this is good for testing atlc create_bmp_for_stripline_coupler(1) For quickly generating bitmaps of directional couplers like this 
Since this structure has an exact analytical result when the conductors are infinitely thin and the groundplanes infinitely wide, it is useful for testing atlc's performance on coupled lines.
design_coupler(1) is quite complex and probably best understood with the use of the HTML-formatted pages, rather than a man page, but one exists for completeness. Running design_coupler -e gives a complete example of the use of design_coupler.dualcoax(1) Computes impedance of a coaxial cable with two
concentric dielectrics. See also coax(1)readbin(1) For finding information on the binary files produced.
sysdata(1) For gathering some hardware infomation.
