       create_bmp_for_symmetrical_stripline  -	bitmap generator for thin con-
       ductor between two infinite groundplanes	(part of atlc)

       create_bmp_for_symmetrical_stripline [-v] W H w bitmapfile

       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
       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	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.

       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

       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.

       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.
