Biniyam Taddese and Steven Anlage demonstrate the sensitivity of electromagnetic sona/coda waves propagating in a ray-chaotic enclosure (the GigaBox) to small perturbations of the wall. They also show the sensitivity of a time-reversed pulse (Loschmidt echo) to the same type of perturbation. See the related paper posted at http://arxiv.org/abs/0812.1118. Thanks to Tom Antonsen for editing.
