An electrodynamic model of a combustion chamber, in which a combustible mixture is ignited by a subcritical streamer discharge initiated with the use of a microwave radiation, is considered. For localization of this discharge in the combustion chamber, its initiator (a vibrator) is positioned parallel to the optical axis of the chamber. On the basis of numerical calculations, the dependences of the structure of the electric field, in which such a discharge is formed, on the geometric parameters of the vibrator and its conductivity have been obtained. For determining an optimum disposition of a vibrator in a combustion chamber, the calculations for its different shifts from the optical axis of the chamber have been performed. The ways of increasing the resultant electromagnetic field in the region of disposition of a vibrator in a combustion chamber for formation of a volume discharge in it were determined.
