Abstract
A plasma generating apparatus includes a vacuum container, an anode and a cathode including multiple electrodes, a power supply for applying a high voltage to the anode and the cathode, and switching elements for switching the electrodes in the anode and the cathode to which the high voltage is applied. The combination of the electrodes are switched by switching elements to form a sheet plasma at any desired angle relative to directional electromagnetic waves.
