Several tests have been performed on High Frequency Ionization. Obviously our researches have evolved since, but here are some pictures of our very first experiences.
In parallel, experiences have been made on parietal ionizers. The first ones were aimed at studying the behavior of a single ionizer. Once the principal was well mastered, the following tests have been performed on a flat surface mounted with a series of similar ionizers, but miniaturized to a size not larger than one millimeter.
For more details about the theoretical aspects of these works, you can read the scientific publication lectured by Jean Pierre Petit during the Bremen (Germany) 2009 international conference dedicated to hypersonic systems :
