skrf.media.cpw.CPW

class skrf.media.cpw.CPW(frequency, w, s, ep_r, t=None, rho=None, *args, **kwargs)

Coplanar waveguide class

This class was made from the technical documentation [1] provided by the qucs project [2] . The variables and properties of this class are coincident with their derivations.
