Claim 8:
9. A plasma actuator that allows an induced flow to be generated, the plasma actuator comprising:
a dielectric layer;
a first electrode and a third electrode that are provided on a front surface of the dielectric layer;
a second electrode and a fourth electrode that are provided on a side of a back surface of the dielectric layer, wherein the second electrode, the third electrode, and the fourth electrode are disposed in this order in one direction from the first electrode in plan view;
a first floating conductor pair provided between the first electrode and the second electrode and including a first front surface conductor disposed on the front surface of the dielectric layer and a first back surface conductor disposed on the side of the back surface of the dielectric layer, wherein the first back surface conductor and the first front surface conductor are disposed in this order in the one direction from the first electrode in plan view and the first front surface conductor and the first back surface conductor are electrically connected to each other and are electrically insulated from the first electrode and the second electrode;
a second floating conductor pair provided between the third electrode and the fourth electrode and including a second front surface conductor disposed on the front surface of the dielectric layer and a second back surface conductor disposed on the side of the back surface of the dielectric layer, wherein the second back surface conductor and the second front surface conductor are disposed in this order in the one direction from the third electrode in plan view and the second front surface conductor and the second back surface conductor are electrically connected to each other and are electrically insulated from the third electrode and the fourth electrode; and
a power supply connected to the first electrode, the second electrode, the third electrode, and the fourth electrode, wherein
the plasma actuator allows the induced flow to be produced along the front surface of the dielectric layer in the one direction from the first electrode by applying a high-frequency high voltage between the first electrode and the second electrode and between the third electrode and the fourth electrode by the power supply to thereby generate dielectric barrier discharge on each of the front surface of the dielectric layer between the first electrode and the first back surface conductor, the front surface of the dielectric layer between the first front surface conductor and the second electrode, the front surface of the dielectric layer between the third electrode and the second back surface conductor, and the front surface of the dielectric layer between the second front surface conductor and the fourth electrode.
