    Abstract

    A microwave applicator that provides a substantially uniform microwave field distribution over a large area, includes an elongated chamber, preferably operating in the length independent mode. A microwave source generates a microwave field at an output frequency. A waveguide or coaxial cable directs the microwave field from the microwave source into the elongated chamber, either through a side launch, end launch or multi launch. A frequency of the microwave field in the elongated chamber and the output frequency of the microwave source are matched through the use of controlled feedback of critical material and process parameters.
