Wave plasma brush: Synthesis and Outlooks

International audience; The aim of this paper is to present the promising outlooks that lies ahead for the innovative plasma source we introduced recently, namely the "wave plasma brush". The idea of this source is to dynamically control the plasma location by changing the waveform of the transmitted signal to a multimode cavity. It is then the behavior of the waves inside the cavity that control the plasma location, hence the name of wave plasma brush. Since its introduction in 2019, we have produced three main papers, aimed at different scientific communities: applied physics, physics of plasma, signal processing and mathematical and numerical methods. An overview of these works is first presented in this paper. Then, the promising outlooks for this unusual plasma source are identified and classified into four domains: unhooking of the plasmas from the antennas in order to control their location anywhere in the cavity, plasma diagnostics, modelling of the problem, and potential applications.
