1 .TH coax 1 "atlc-4.6.0 28th Oct 2003" "Dr. David Kirkby"
4 \fBcoax\fR - determine impedance of a coaxial structure, where the inner may be offset from the centre if
7 \fBcoax [-O offset] d D Er\fR
10 coax computes the impedance of a coaxial cable, given the
11 outside diameter of the inner conductor d, the internal diameter of the outer
12 conductor D and the relative permittivity of the dielectric Er. If there is
13 an offset between the inner and outer (i.e. the coax is eccentric),
14 the offset can be given as a option. coax uses the
18 Zo=59.95849160 ln(x+sqrt(x^2-1)) /sqrt(Er) Ohms
21 where x=(d^2+D^2-4 O^2)/(2*D*d)
25 coax does not read/write any files.
