Research output: Patent


In an embodiment of the invention there is a cyclotronic actuator. The actuator is defined by having a high-voltage plasma driver connected to a first electrode. The first electrode is surrounded by a dielectric material. A second electrode is grounded and placed away from the first electrode, such that a plasma arc is formed between the pair of electrodes when the high-voltage plasma driver is activated. A ring magnet surrounding the second electrode is configured to introduce a magnetic field locally to the plasma arc. The plasma arc will then discharge in a radial direction. The magnet creates a local magnetic field oriented vertically in a direction parallel to the axisymmetric orientation of the first and second electrodes to create a Lorentz Force. The force causes the plasma arc to move in a tangential direction and causes the plasma arc to discharge out in a circular pattern.
