Time Reflection of Electromagnetic Waves Demonstrated in a Groundbreaking Experiment...

[Fred Bloggs]

Scientists have hypothesized for over six decades the possibility of observing a different form of wave reflections, known as temporal, or time, reflections. In contrast to spatial reflections, which arise when light or sound waves hit a boundary such as a mirror or a wall at a specific location in space, time reflections arise when the entire medium in which the wave is traveling suddenly and abruptly changes its properties across all of space. At such an event, a portion of the wave is time-reversed, and its frequency is converted to a new frequency.

Looks like a distributed reflection process to me- switched in some lumped capacitance loading along the line..
