Time Reversal – Hole Burning

We present a counterintuitive method to create a time-reversed wave by applying a time-controlled dissipation pulse. Moreover, by successive application of this principle, we can destroy a monochromatic component of a broad band wave to make an “in situ” spectral hole burning We demonstrate this technique numerically and an experimental proof is made with a system composed of levitating repelling magnets.
