Abstract

We report the experimental demonstration of plasma generation by time-reversal focusing. After a learning phase, the amplified time reversed signal built at a central frequency of 2.45 GHz injected in a low loss metallic cavity allows to ignite and maintain a localized centimer-sized plasma in argon at 133 Pa. The plasma spatial position is totally controlled by the signal waveform.
