Opis

Guided-Wave-Produced Plasmas provides an up-to-date report of the physics of plasmas produced by the high-frequency electromagnetic fields of guided waves. The modelling of discharges generated by travelling surface waves is presented using a unified approach based on modern aspects of nonlinear plasma theory. Diagnostic methods needed for research and the main experimental results on plasma behaviour are covered in detail. The methods and ideas presented in this book possess great potential for a wide variety of applications in plasma technology.
