20090015489 | DEVICE FOR COUPLING BETWEEN A PLASMA ANTENNA AND A POWER SIGNAL GENERATOR - The present invention relates to a device for coupling between a plasma column serving as an antenna and an electric power signal generator, associated with a laser. This device comprises at least two conducting electrodes, each pierced with a hole, these holes being coaxial, the electrodes being connected on the one hand to a high voltage direct current source and on the other hand to power signal alternating current source, the laser(s) being placed do that its (their) beam arrives along the axis of said holes of the electrodes. | 01-15-2009 |
20090284421 | RF antenna assembly having an antenna with transversal magnetic field for generation of inductively coupled plasma - An antenna assembly that consists of a holder which supports a transversal RF antenna with a plurality of multiturn coils connected in series or in parallel and intended for generation of an inductively coupled plasma discharge inside a container with a high plasma density in vicinity of the container's inner walls. The aforementioned discharge is used for inducing in the container a plasma chemical reaction between oxygen and organosilane with resulting deposition of the reaction product in the form of silicon dioxide onto the inner walls of the container for forming a fluid-impermeable barrier layer. A specific feature of the antenna is that it generates a magnetic field transversal to the longitudinal axis of the antenna, i.e., normal to the container's walls, where a maximal electric field, maximal plasma density and, correspondingly, maximal rate of deposition of silicon dioxide on the wall are provided. | 11-19-2009 |
20090315784 | ANTENNA STRUCTURE FOR A MAGNETIC RESONANCE DEVICE - An antenna structure for a magnetic resonance device constructed as a radiating or transmitting antenna of the magnetic resonance device, has a non-metallic antenna conductor containing a discharge gas. When energy is imparted to the discharge gas, the antenna conductor forms an electrically conducting gas discharge column and can be used as an electrically conducting antenna element. | 12-24-2009 |
20110025565 | PLASMA DEVICES FOR STEERING AND FOCUSING ANTENNA BEAMS - A plasma array of plural plasma containers of selected shapes and a selected spacial distribution, contain variable plasma density within each container and from one container to the next for establishing plasma frequency ranges from zero to an arbitrary plasma frequency. The plasma array is operating in a mode to transmit, receive, filter, reflect and/or refract radiation. | 02-03-2011 |
20110148717 | Shock wave modification method and system - A system for modifying a shock wave formed in a fluid by a body to modify effects of the shock wave on information transferred to or from the body. The system includes laser pulses for heating fluid along a path to form a volume of heated fluid expanding outwardly from the path, the path extending from the body and through the shock wave; an element for transferring the information to or from the body; and a timer for timing the transferring of the information relative to the heating of the fluid along the path to modify certain effects of the shock wave on the information. | 06-23-2011 |
20110163920 | METHOD AND APPARATUS FOR AN OPTICAL FREQUENCY RECTIFIER - The present invention is a method and apparatus for receiving and converting incident radiation into DC current. The method begins with selection of an antenna having a terminal tip with a sharp edge. The antenna is layered with a substrate and a first coating. A first electrode and a metallic/mCNT antenna are layered on the first coating, and a plasmonic layer is then added. A gap is formed which is bounded on one side by the terminal ends of the plasmonic layer and the first coating, and a second electrode and a second coating on the other. The second electrode is layered upon the second coating which is layered upon the substrate. A set of AC currents is induced along the length of the antenna. The method then calculates whether or not the induced AC currents are large enough to create voltages for field emission. If the voltages are large enough, then a forward bias and a reverse bias are initiated. Due to the asymmetry in these tunneling barriers, a positive net DC current is delivered to an external circuit. | 07-07-2011 |

20140333485 | PLASMA AVIATION ANTENNA - An aircraft communications system may include a RF-transparent enclosure, a plasma antenna element and a controller. The RF-transparent enclosure may be disposed substantially conformal with a portion of the aircraft. The plasma antenna element may be housed within the RF-transparent enclosure. The controller may be operably coupled to the plasma antenna element to provide control of operation of the plasma antenna element. The plasma antenna element may include one or more RF-conductive plasma devices that are selectively ionized to a plasma state under control of the controller. | 11-13-2014 |
20160149287 | PLASMA-INTEGRATED SWITCHING DEVICES - A switching device includes a first electrode at least partially disposed within a sealed chamber. The sealed chamber encloses a plasma phase change material. The switching device includes a second electrode at least partially disposed within the sealed chamber. The second electrode is physically separated from the first electrode. When subjected to a signal that satisfies a threshold, the plasma phase change material forms a plasma within the sealed chamber. The first electrode is electrically coupled to the second electrode via the plasma when the plasma is formed. The first electrode is electrically isolated from the second electrode when the plasma is not formed. The switching device includes a first connector electrically coupled to the first electrode and a second connector electrically coupled to the second electrode. The first connector, the second connector, or both, are configured to receive the signal. | 05-26-2016 |
