Secure Communication with Nonlinear Time-Reversal: This figure demonstrates secure communication of two different UMD images using nonlinear time-reversal of electromagnetic waves (signals); each sent through a complicated wave scattering environment (brown box in the middle). The black boxes represent time-reversed signals that are not reconstructed after being scattered" title="Secure Communication with Nonlinear Time-Reversal: This figure demonstrates secure communication of two different UMD images using nonlinear time-reversal of electromagnetic waves (signals); each sent through a complicated wave scattering environment (brown box in the middle).

Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable electronics, even a listening device hiding in a prosthetic toe, without knowing where it is….
