% Functions to calculate coaxial cable parameters.
%
% coaxAlpha - attenuation constant of coaxial cable
% coaxC - capacitance of coaxial cable per unit lenght (Farad/meter)
% coaxG - shunt conductance of coaxial cable per unit lenght (1/Ohm*meter)
% coaxGamma - propagation constant of coaxial cable
% coaxL - inductance of coaxial cable per unit lenght (Henry/meter)
% coaxR - resistance of coaxial cable per unit lenght (Ohm/meter)
% deltaS - skin depth of conductor at frequency freq (meters)
% impedanceZ0 -characteristic impedance of coaxial cable (Ohm)
% impedance - impedance at the end of coax of certain lenght(meter) connected 
%              to a given load (compex Ohm)
% rho - reflection coefficient of a load with impedance ZL connected to a 
%               a cable with impedance Z0 (complex ohms)
% SWR(rho) - standing wave ratio at any point in a waveguide if reflection 
%               coefficient given
% velocity(epsilonR,muR) - wave velocity of coaxial cable
