This is the command coax that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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
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)
