NAME
coax - determine impedance of a coaxial structure, where the inner may be offset from the centre if necessary.
SYNOPSIS
coax [-O offset] d D Er
DESCRIPTION
coax computes the impedance of a coaxial cable, given the outside diameter of the inner conductor d, the internal diameter of the outer
conductor D and the relative permittivity of the dielectric Er. If there is an offset between the inner and outer (i.e. the coax is eccen-
tric), the offset can be given as a option. coax uses the equation
Zo=59.95849160 ln(x+sqrt(x^2-1)) /sqrt(Er) Ohms
where x=(d^2+D^2-4 O^2)/(2*D*d)
