Electromagnetic Modeling of a Plasma Chamber: Theory and Experiments

We propose finite element method — based models facilitating simulation of tuned plasma discharges in an argon atmosphere. The models, in which we focused on the adjustment options and relevant numerical analyses, allowed us to design a plasma discharge jet and to characterize the behavior of a discharge therein. A set of functional experiments were performed, evaluated, and compared throughout the research. Overall, the plasma chamber finds use in surface treatment at a nanometric distance from the material-air interface; such a procedure can produce special layers of inorganic/organic materials conceived as resonant structures. The paper exposes the ability of a plasma discharge to operate as a parametric instrument that alters the electromagnetic and mechanical properties on the surface of the applied material.
