The plasma generator has the dielectric having the inner circumferential surface, and a pair of electrodes which are arranged separated from each other in the direction along the inner circumferential surface and are isolated from each other by the dielectric and which are capable of generating plasma on the inner circumferential surface by application of voltage. In the inner circumferential surface, at the positions between the pair of electrodes in a plan view, recessed portions causing electric field concentration are formed.

Plasma generator and plasma generating device

Provided is an ion wind generator capable of suitably generating an ion wind along the surface of a dielectric. An ion wind generator has: a dielectric having a first primary surface and a second primary surface at the rear thereof; an inner side electrode arranged in the dielectric; a first electrode arranged on the first primary surface side with respect to the inner side electrode; and a second electrode arranged on the second primary surface side with respect to the inner side electrode. The inner side electrode has a first downstream area located in a first direction (the positive side of x-axis direction) along the first primary surface with respect to the first electrode, and a second downstream area located in a second direction (the positive side of x-axis direction) along the second primary surface with respect to the second electrode.

Ion wind generator and ion wind generating device

Provided is an ion wind generator capable of diversifying either or both of the amount of wind or wind direction. An ion wind generator is provided with a first electrode, a second electrode having a downstream area which is arranged at a position in a plan view shifted from first electrode towards the positive side in the x direction, and a dielectric between the first electrode and the second electrode. In a plane view, the distance (d) in the x-direction from a downstream side edge of the first electrode to the downstream side edge of the downstream area differs in the y-direction which is perpendicular to the x-direction.

A plasma generator has a first membercontaining a dielectric material, and an electrode group composed of a plurality of electrodes and including a first assemblypartially including a plurality of electrodes and a second assemblypartially including a plurality of electrodes. In accordance with an AC voltage, the first assemblygenerates a plasma in a first spacecontacting the first member. In accordance with a DC voltage, the second assemblygenerates an electric field in a second spacecontacting the first memberand communicating with the first space. At least one or more electrodes of a portion of the first assemblyand at least one or more electrodes of a portion of the second assemblyare provided on the surface of or in the inside of the first member
