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  permit-
     tivity  of  the dielectric Er. If there is an offset between
     the inner and outer (i.e. the coax is eccentric), 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)
