Abstract
Cette invention a trait à une technique d'incision d'un matériau au moyen d'un nuage de plasma équilibré. Un générateur à fréquences radioélectriques et un amplificateur de puissance peu onéreux produisent une onde électromagnétique émise à partir d'une sonde à inciser émettrice. Cette onde électromagnétique est adaptée en impédance, en fréquence et en puissance, ce qui permet la génération et le maintien en l'état d'un nuage de plasma équilibré, à faibles turbulence et chaos des particules atomiques, qui forme une couche au-dessus de la surface de la pointe à inciser et contribue à réduire la demande énergétique qui est exigée de l'amplificateur. On utilise également cette onde électromagnétique pour engendrer un effet de rétrécissement et ce, afin de comprimer le nuage de plasma, en définir les contours, lui donner une forme et le maîtriser. On utilise, de surcroît, cette onde électromagnétique pour piéger et contenir le nuage de plasma sans devoir recourir à une cuve de confinement, faite d'un matériau solide, en conformité avec l'effet physique de la bouteille magnétique. On utilise l'effet tunnel de la chimie physique pour amplifier l'énergie envoyée au nuage plasmatique équilibré tout en protégeant la matière entourant le trajet d'incision prévu d'une éventuelle exposition aux rayonnements. Ce système permet de procéder à une incision dans un matériau de façon efficace, en toute sécurité, proprement et à peu de frais.
