Plasma reactor for processing gas

A plasma generating system, comprising:

• a waveguide for transmitting a microwave energy therethrough;
• an inner wall disposed within the waveguide to define a plasma cavity, a plasma being generated within the plasma cavity using the microwave energy;
• a first flow inlet mounted on a bottom side of the waveguide and including one or more passageways through which a first gas is introduced into the plasma cavity and configured to generate a first vortex flow within the plasma cavity using the first gas, the first flow inlet having a through hole through which a gas that is processed by the plasma and moves toward the bottom side of the waveguide exits the plasma cavity;
• and
• a plasma stabilizer having a shape of a circular hollow cylinder and installed on a a top side of the waveguide and protruding into the plasma cavity, a longitudinal direction of the plasma stabilizer being parallel to a rotational axis of the first vortex flow,
• wherein the one or more passageways of the first flow inlet are disposed on the bottom side of the waveguide.
