An original approach based on a time reversal technique is proposed to fabricate a wireless transmission of electromagnetic energy for indoor applications. Experiments performed in a low-Q cavity of human size with a carrier frequency around 2.45 GHz show that the energy efficiency is greater than the one obtained with a continuous wave approach.
