Taking advantage of multiple scattering to communicate with time-reversal antennas.

摘要: We present an experimental demonstration showing that, contrary to first intuition, the more scattering a mesoscopic medium is, information can be conveyed through it. used multiple input-multiple output configuration: multichannel ultrasonic time-reversal antenna is transmit random series of bits simultaneously different receivers which were only few wavelengths apart. Whereas transmission free error when occurs in propagation medium, rate huge homogeneous medium.
