  • Electrode for a plasma generator
    Patent number: 8339047
    Abstract: The invention relates to an electrode for a plasma generator for generating plasmas at atmospheric pressure or near-atmospheric pressures by means of excitation using microwaves. The invention provides an electrode made of a sheet metal strip (1), in the longitudinal direction of which at least one slot (2) is introduced at a length that is one time or multiple times that of a quarter of the wavelength of the open-circuit voltage of the microwave such that at least two partial electrodes (3) are formed, wherein the voltage supply line is provided on the partial electrodes (3) in the region of the closed slot end or ends.
