posted on 2009-08-25, 15:46 authored by Z. Cao, James L. Walsh, Michael G. KongThis letter reports on electrical and optical characteristics of a ten-channel atmospheric pressure
glow discharge jet array in parallel electric and gas flow fields. Challenged with complex
three-dimensional substrates including surgical tissue forceps and sloped plastic plate of up to 15°,
the jet array is shown to achieve excellent jet-to-jet uniformity both in time and in space. Its spatial
uniformity is four times better than a comparable single jet when both are used to treat a 15° sloped
substrate. These benefits are likely from an effective self-adjustment mechanism among individual
jets facilitated by individualized ballast and spatial redistribution of surface charges.
