#### Power-Complementary Reflection and Transmission

We can show that the reflectance and transmittance of the yielding termination are*power complementary*. That is, the reflected and transmitted signal-power sum to yield the incident signal-power.

The average power incident at the bridge at frequency can be expressed in the frequency domain as . The reflected power is then . Removing the minus sign, which can be associated with reversed direction of travel, we obtain that the

*power reflection frequency response*is , which generalizes by analytic continuation to . The power transmittance is given by
