As I finished writing the post, I wanted to call attention to the assumption that the reflected power is true power and adds to the amount of energy "stored" on the transmission line. But "stored" is a word that implies static conditions, and static conditions are not found on a transmission line. So I substituted "present" for "stored.

The amount of energy existing in a transmission
line is exactly the amount required to support
the measured forward power and reflected power.

If the steady-state forward power is 200 watts,
the reflected power is 100 watts, and the lossless
transmission line is one microsecond long, it
contains 300 microjoules of energy. I don't
think that is a sheer coincidence. :-)
