20100041559 | TUNABLE, SUPERCONDUCTING, SURFACE-EMITTING TERAHERZ SOURCE - A compact, solid-state THz source based on the driven Josephson vortex lattice in a highly anisotropic superconductor such as Bi | 02-18-2010 |
20100264312 | SUPERCONDUCTING SOURCE FOR TUNABLE COHERENT TERAHERTZ RADIATION - A system includes a solid state source of THz radiation and a detector. The source of THz radiation may be based on a superconducting material, such as materials containing one or more Josephson junctions (e.g. BSCCO). The source may include a crystal of superconducting material on which a mesa of superconducting material is formed. The resonant coupling between the Josephson oscillations and the fundamental cavity mode of the mesa may lead to synchronization of the Josephson junctions and emission of powerful THz radiation. The mesa may be formed and/or handled such that THz radiation can be emitted by the material without requiring application of an external magnetic field (e.g. the mesa may include a non-uniform compositional gradient, a non-uniform shape, may have radiation non-uniformly applied to the mesa, etc.). | 10-21-2010 |

20150311058 | LIGHT SOURCE WITH LASER PUMPING AND METHOD FOR GENERATING RADIATION - The invention relates to light sources with laser pumping and to methods for generating radiation with a high luminance in the ultraviolet (UV) and visible spectral ranges. The technical result of the invention includes extending the functional possibilities of a light source with laser pumping by virtue of increasing the luminance, increasing the coefficient of absorption of the laser radiation by a plasma, and significantly reducing the numerical aperture of a divergent laser beam which is to be occluded and which is passing through the plasma. The device comprises a chamber containing a gas, a laser producing a laser beam, an optical element, a region of radiating plasma produced in the chamber by the focused laser beam, an occluder, which is mounted on the axis of the divergent laser beam on the second side of the chamber and an optical system for collecting plasma radiation. | 10-29-2015 |

20100082724 | Method For Solving Reservoir Simulation Matrix Equation Using Parallel Multi-Level Incomplete Factorizations - A parallel-computing iterative solver is provided that employs a preconditioner that is processed using parallel-computing for solving linear systems of equations. Thus, a preconditioning algorithm is employed for parallel iterative solution of a large sparse system of linear system of equations (e.g., algebraic equations, matrix equations, etc.), such as the linear system of equations that commonly arise in computer-based 3D modeling of real-world systems (e.g., 3D modeling of oil or gas reservoirs, etc.). A novel technique is proposed for application of a multi-level preconditioning strategy to an original matrix that is partitioned and transformed to block bordered diagonal form. An approach for deriving a preconditioner for use in parallel iterative solution of a linear system of equations is provided. In particular, a parallel-computing iterative solver may derive and/or apply such a preconditioner for use in solving, through parallel processing, a linear system of equations. | 04-01-2010 |
