Dielectric electrode assembly and method of manufacture thereof

A method of manufacture of a dielectric electrode assembly comprising:

• providing a dielectric tube having an elliptical cross-section and a relative dielectric constant, ε2, the dielectric tube filled with a gas having a relative dielectric constant, ε1;
• surrounding the dielectric tube with a structural dielectric having a relative dielectric constant, ε3;
• positioning metal electrodes on opposite sides of the structural dielectric, the metal electrodes having a flat cross-sectional geometry;
• and
• selecting a material for the structural dielectric such that the relative dielectric constants of the structural dielectric, the dielectric tube, and the gas are interrelated and an electric field of at least 90% uniformity is generated within the dielectric tube when power is applied to the metal electrodes.
