Time reversed pulse waves study for wireless energy transmission in a low Q cavity

Résumé

An original approach based on time reversal technique is studied for wireless energy transmission with electromagnetic waves. Experiments around 2.45 GHz are performed in a low-Q cavity of human size approaching real indoor environment. It is shown that, in order to increase the amplitude of the focused signals on a specific spot using time reversal technique, expanding the bandwidth of the emitted signals is needed. In addition, focused spot dimension is theoretically and experimentally illustrated. Other potential benefits of the time reversal technique are discussed and the superiority of energy performance of this technique compared to others (e.g. Inverse Filter and Continuous Wave) is demonstrated.
