Yes, Cecil caught me not paying attention. At an open circuit, the
impedance is infinite but the coefficient of reflection is the ratio of
the voltage of the reflected wave to the voltage of the incident wave.
As both have the same phase and magnitude, value of the reflection
coefficient for an open circuit is 1.0, not infinity.
