An experimental verification of the excitation power of a transmission line with a shunt load

The excitation power of a scattering body is governed, in general, by a forward scattering theorem. In some special cases, the backward scattering formula yields the same result. A transmission line with a shunt impedance load is one of the examples where the excitation power is proportional to the real part of the product between the incident voltage and the conjugate of the backward scattering current, which is equal to the negative of the product of the incident voltage and the conjugate of the forward scattering current. In this work, an experiment has been performed to verify the above result.
