Plasma Processes and Polymers, 4 (2007), 266 - 274.

Recently, there has been increased interest in using atmospheric pressure plasmas for
materials processing, since these plasmas do not require expensive vacuum systems. However,
APGDs face instabilities. Therefore, special plasma sources have been developed to overcome
this obstacle, which make use of DC, pulsed DC and AC ranging
from mains frequency to RF. Recently, the APPJ was introduced,
which features an a-mode of an RF discharge between two bare
metallic electrodes. Basically, three different geometric configurations
have been developed. A characterization of the APPJs and
their applications is presented.
