A plasma generator capable of separating a microwave propagation band from an absorption band

摘要

The present invention relates to a dispersing device for dispersing microwave energy to energize a plasma in a closed section. According to the invention, the dispersing device comprises at least one second irradiator (p2) working together with the first irradiator (p1) and the exciter (e) to form at least one triplet excitation element. The first irradiator p1 and the second irradiator p2 are mounted parallel to each other and spaced apart therebetween to define a microwave energy propagation band P and the exciter e is connected to the first and second irradiators P1 The exciter is arranged in such a manner that the trajectory P of the electrons does not cross the propagation band P and the propagation band P and the absorption band A are separated from each other.
