Abstract:
1. An induction concentration remote atmospheric pressure plasma generating apparatus, comprising: a hot electrode having one or more holes; induction electrodes disposed within the hot electrode holes, wherein the hot electrode holes and the induction electrodes are spaced apart from each other at predetermined intervals; a dielectric material surrounding the hot electrode and the induction electrodes, wherein the induction electrodes are projected downwardly from the dielectric material; a spring disposed below the induction electrodes; a discharge electrode disposed below the spring, wherein a lower side of the induction electrode, the spring and the discharge electrodes are located within a discharge electrode holding hole of a ceramic dielectric material having a narrow discharge hole; a ground electrode having a small hole and disposed below the narrow discharge hole of the ceramic dielectric material, the ground electrode being grounded; and a chamber for accommodating the above constituent elements and having a working gas supply unit for supplying a working gas.
