The SI unit of characteristic impedance is the Ohm . DESCRIPTION A uniform line terminated in its characteristic impedance will have no Standing Wave s, no reflections from the end, and a constant ratio of voltage to current at a given Frequency at every point on the line. The characteristic impedance of a linear, homogeneous, Isotropic , Dielectric Propagation Medium free of electric charge is given by the relation : where :is the characteristic impedance :is the electric Permittivity of the medium (in Farads per meter) :is the magnetic Permeability of the Medium (in Henries per meter) : is the speed of propagation in the medium When the medium is Free Space , the magnetic permeability and electric permittivity of free space are used and this defines the universal Physical Constant , the characteristic impedance of free space: : where : is the Speed Of Light in free space, : is the Permittivity Of Free Space , and : is the Permeability Of Free Space .
