Patent number: 6818193Abstract: A plasma reactor including a first dielectric having at least one capillary defined therethrough, and a segmented electrode including a plurality of electrode segments, each electrode segment is disposed proximate an associated capillary. Each electrode segment may be formed in different shapes, for example, a pin, stud, washer, ring, or disk. The electrode segment may be hollow, solid, or made from a porous material. The reactor may include a second electrode and dielectric with the first and second dielectrics separated by a predetermined distance to form a channel therebetween into which the plasma exiting from the capillaries in the first dielectric is discharged. The fluid to be treated is passed through the channel and exposed to the plasma discharge. If the electrode segment is hollow or made of a porous material, then the fluid to be treated may be fed into the capillaries in the first dielectric and exposed therein to the maximum plasma density.Type: GrantFiled: December 15, 2000Date of Patent: November 16, 2004Assignees: Plasmasol Corporation, Stevens Institute of Technology, LLCInventors: Christos Christodoulatos, George Korfiatis, Richard Crowe, Erich E Kunhardt

Patent number: 6178275Abstract: The present invention relates to a method and apparatus for the generation, manipulation and detection of plasmon, and/or solitons, both linear and non linear, in semi-conductor heterostructures. The apparatus includes a galium arsonide substrate, a two-dimensional electron gas well (2-DEG) (160) form thereon and a thin layer of Aluminum galium arsonide (AlGaAs) placed thereover. Launcher (130) and receiver lines (132, 134, 136) are formed on the AlGaAs layer. Each of the launcher (130) and receiver lines (132, 134, 136) includes coplanar waveguides which preferably consist of two to three metal lines. One line is interconnected with a photoconductive switch (120) and can be pulsed. The other line or lines are grounded. Pulsing the line forms an electric field which can be detected. Between the launcher and (130) and the receiver (140), the plasmon can be modulated by one or more additional gates line extending over the 2-DEG.Type: GrantFiled: April 19, 2000Date of Patent: January 23, 2001Assignee: The Trustees of the Stevens Institute of TechnologyInventors: Annita Nerses, Erich E.

Patent number: 6147452Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated or apertured dielectric plate having an upper surface and a lower surface and one or more holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength. In another embodiment, the device comprises an AC glow plasma discharge device wherein an apertured dielectric is placed over an electrode. The apertured dielectric may have one or more apertures or capillaries extending therethrough.Type: GrantFiled: September 16, 1998Date of Patent: November 14, 2000Assignee: The Trustees of the Stevens Institute of TechnologyInventors: Erich E.
