Here is a small java program demonstrating wave energy transfer in 1D space.

The Start button will restart the demonstartion at any time.

The next button toggles between a sine wave and a square wave.

Zmean is the normal impedance used to calculate values.

Gain is the total transfer gain and can vary between 0 and 2.0.

Zr is the impedance at the extreme right end of the simulation. Setting this to a value less than Zmean will reflect the wave back out of phase and a value higher than Zmean will reflect a wave back in phase.
