PLASMA GENERATING DEVICE, AND INTERNAL COMBUSTION ENGINE

摘要

In order to enlarge the plasma generation region of a plasma generating device for generating plasma by using electromagnetic waves, a plasma generating device is provided with: an electromagnetic wave generating device for generating electromagnetic waves; a radiating antenna for radiating the electromagnetic waves, supplied by the electromagnetic wave generating device, toward a target space; and a receiving antenna which is in close proximity to the radiating antenna, and which has been earthed such that the voltage of a near-section which is in close proximity to the radiating antenna is relatively high throughout the period during which electromagnetic waves are being radiated from the radiating antenna. The plasma generating device generates plasma in close proximity to the near-section and in close proximity to the radiating antenna in the target space by radiating electromagnetic waves from the radiating antenna.
