PLASMA GENERATING DEVICE, AND INTERNAL COMBUSTION ENGINE

摘要

To simplify a configuration of a plasma generation device that generates plasma by means of an electromagnetic wave using thermal electrons as a trigger. The plasma generation device 30 includes: a thermal electron emission member 14 that emits thermal electrons when heated; a heating device 13 that heats the thermal electron emission member 14 by means of an electromagnetic wave; and an electric field concentration member 61 that concentrates in the vicinity of the thermal electron emission member 14 an electric field of the electromagnetic wave generated by the heating device 13. The plasma generation device 30, while causing the heating device 13 to heat the thermal electron emission member 14, causes the electric field concentration member 61 to concentrate the electric field of the electromagnetic wave in the vicinity of the thermal electron emission member 14, thereby generating plasma in the vicinity of the thermal electron emission member 14.
