Abstract :
The main source of the gas ionization and plasma producing in microwave plasmatrons is electromagnetic energy of microwaves. Therefore, precise knowledge of microwave field is important for understanding mechanism of the plasma origin and constructing the plasma sources. The direct computation of the field in complicate structures was chosen to find an optimized shape of the plasmatron end unit. The maximum value of the electromagnetic field determines the activation energy, which in turn determines the origin of the discharge.
