Artificial dielectric device for heating gases with electromagnetic energy

Device which uses applied electromagnetic energy for treatment of a chemical species flow comprising, in combination:

• (a) a cavity which has a cross-sectional area that is normal to the flow of the chemical species flow, said cross-sectional area being shaped as an irregular-shaped polygon of four (4) or more sides, wherein the two sides that are parallel to each other are elongated, producing the greatest dimension of the said cross-sectional area known as the length;
• (b) at least one opening located on each parallel side of the greatest dimension of the said cross-sectional area as a means for the applied electromagnetic energy to enter the cavity;
• (c) an inlet where the chemical species flow enters the cavity with said inlet having a means to prevent the applied electromagnetic energy from escaping the cavity;
• (d) a gas-permeable susceptor which provides a means for a desired treatment of the chemical species flow by volumetric interaction with the applied electromagnetic energy by having the depth of penetration of said susceptor by the applied electromagnetic energy being no less then one-third the width of the said susceptor, where a least 50% of the applied energy in the cavity volumetrically interacts with said susceptor by the volume that is given by the product of the width of interaction by the said susceptor's breadth by the said susceptor's length having the cavity extended in the direction of the breadth of the cavity as a means to provide a designed resident time for the desired treatment of the chemical species flow;
• and
• (e) an outlet where the treated chemical species flow leaves the cavity with said outlet having a means to prevent electromagnetic energy from escaping the cavity.
