create_bmp_for_symmetrical_sGeneraleComcreate_bmp_for_symmetrical_stripline(1) NAME create_bmp_for_symmetrical_stripline - bitmap generator for thin con- ductor between two infinite groundplanes (part of atlc) SYNOPSIS create_bmp_for_symmetrical_stripline [-v] W H w bitmapfile WARNING This man page is not a complete set of documentation - the complexity of the atlc project makes man pages not an ideal way to document it, although out of completeness, man pages are produced. The best docu- mentation that was current at the time the version was produced should be found on your hard drive, usually at /usr/local/share/atlc/docs/html-docs/index.html although it might be elsewhere if your system administrator chose to install the package elsewhere. Sometimes, errors are corrected in the documentation and placed at http://atlc.sourceforge.net/ before a new release of atlc is released. Please, if you notice a problem with the documentation - even spelling errors and typos, please let me know. DESCRIPTION create_bmp_for_symmetrical_stripline is a pre-processor for atlc, the finite difference program that is used to calculate the properties of a two-conductor electrical transmission line of arbitrary cross section. The program create_bmp_for_symmetrical_stripline is used as a fast way of generating bitmaps (there is no need to use a graphics program), for a 1 pixel thick conductor of width w, centrally located inside a pair of groundplanes of width W and separation H. This has an exact analyti- cal answer, when the inner is infinitely thin and the width W is infin- itely wide. This theoretical impedance is also calculated by the cre- ate_bmp_for_symmetrical_stripline. It is therefore used as a test of atlc. ----------------------------------------------------- ^ | | | | | | | <----------w-----------> | | | | H | | | | | | ----------------------------------------------------- v <-------------------------W-------------------------> The parameters 'W' and 'H' and the inner dimensions of the outer con- ductor. The outer dimensions of the inner conductor are 'w' and 'c'. The inner conductor is assumed to rest on a dielectric (Er2) which is 'd' wide and outer conductor an the inner conductor is offset 'b' from the left hand sidewall of the outer conductor. The whole region is sur- rounded by a dielectric of relative permittivity 'Er1'. The dielectrics 'Er1' and then 'Er1' and 'Er2' will both be 1.0 The bitmaps produced by create_bmp_for_symmetrical_stripline are 24-bit bit colour bitmaps, as are required by atlc. Currently cre- ate_bmp_for_symmetrical_stripline only produces bitmaps with white (vacuum) dielectrics. OPTIONS -v Print the theoeretical impedance Zo. This only works if the width W is sufficiently wide, otherwise atlc and the value printed here would dis- agree wildly.
