Transfer impedance is used to determine shield effectiveness at lower frequencies (< 1 GHz) against both ingress and egress of interfering signals. Cable shields are normally designed to reduce the transfer of interference, hence, shields with lower transfer impedance are more effective than shields with higher transfer impedance.

Admittance in the Reflection Coefficient Plane. Commonly, transmission lines are interconnected in parallel. It is then convenient to work with the admittance rather than the impedance. The Smith chart describes equally well the evolution of the admittance with z. With Y o = 1/Z o defined as the characteristic admittance, it follows from (1) thatImpedance is the combination of resistance and reactance (both inductive and capacitive) and is a complex number, containing both real and imaginary parts.
