62 APPARATUS FOR GENERATING FOCUSED ELECTROMAGNETIC RADIATION US15489160 2017-04-17 US20170323697A1 2017-11-09 Arzhang Ardavan; Houshang Ardavan
An apparatus for generating electromagnetic radiation comprises a polarizable or magnetizable medium. A polarization or magnetisation current can be generated, in a controlled manner, whose distribution pattern has an accelerated motion, so that non-spherically decaying and intense spherically decaying components of electromagnetic radiation can be generated. The coordinated motion of aggregates of charged particles can give rise to extended electric charges and currents. The charged distribution patterns can propagate with a phase speed exceeding the speed of light in vacuo and that, once created, such propagating charged patterns act as sources of electromagnetic fields in precisely the same way as any other moving sources of these fields. That the distribution patterns of these sources travel faster than light is not, of course, in any way incompatible with the requirements of special relativity. The superluminally moving charged pattern is created by the coordinated motion of aggregates of subluminally moving particles.

67 EUV LIGHT SOURCE FOR GENERATING A USABLE OUTPUT BEAM FOR A PROJECTION EXPOSURE APPARATUS US14636413 2015-03-03 US20150173163A1 2015-06-18 Ingo Saenger; Manfred Maul; Christoph Hennerkes; Johannes Ruoff; Daniel Kraehmer
An EUV light source serves for generating a usable output beam of EUV illumination light for a projection exposure apparatus for projection lithography. The light source has an EUV generation device which generates an EUV raw output beam. The latter is circularly polarized. For the purposes of setting the polarization of the usable output beam and in respect of the polarization direction, a polarization setting device has a linearly polarizing effect on the raw output beam. This results in an EUV light source, which provides an improved output beam for a resolution-optimized illumination.

The emitted radiation no longer has any sidelobes in the far field and its characteristic has a Gaussian profile over the azimuth angle.

75 Wave mode converter US863235 1977-12-22 US4175830A 1979-11-27 Georges R. P. Marie
Mode converter for electromagnetic, light or infrared waves. This mode converter converts particle non-confining modes to particle confining modes. In a confining mode wave beam the phase of the wave with respect to time at a point of the beam having a given azimuth with respect to the beam axis is proportional to this azimuth. Two types of mode converter are disclosed. In the first type, the wave passes through a block of transparent isotropic material the thickness of which is proportional to the azimuth around the beam axis. In the second type, the converter is formed with triangular or sectoral plates of birefringent material and in each plate the slow and fast axes are given an adequate orientation.
76 Dielectic refrigerator using orientable defect dipoles US755890 1976-12-30 US4136525A 1979-01-30 James A. Van Vechten
This disclosure describes a dielectric refrigerator using orientable defect dipoles and operating between a high temperature, T.sub.h reservoir illustratively supplied by a Stirling cycle refrigerator (8.degree. K .ltoreq. T.sub.h .ltoreq. 20.degree. K) and a low temperature, T.sub.1, load, illustratively the liquid He cooling fluid for Josephson junction or other superconducting devices (2.degree. K .ltoreq. T.sub.1 .ltoreq. 6.degree. K).Exemplary practice of this invention provides cooling from the limit of a refrigerator based on the Stirling thermodynamic cycle (20 to 8.degree. K) to operating temperatures of common and useful superconductive devices (3 to 6.degree. K). Orientable electric dipoles of defects in electrically insulating materials, e.g., crystals, are utilized to provide cooling in the range from (8-20 K) to (2-6.degree. K). The following are particular considerations concerning the practice of this invention: use of LiF, MgO and BeO as host crystals; use of OH and/or NH.sub.2 as defects in LiF, and use of HF, HCl, HBr and/or NH as defects in MgO or BeO; mechanical or electromechanical means to make and break thermal contact between dielectric crystal and load and between load and reservoir; and use of thermal rectifiers to obviate the need for thermal switches in order to transfer heat from the load to the refrigerator material and thence to the reservoir.

78 Collection of ions in a plasma by magnetic field acceleration with selective polarization US428661 1973-12-27 US3959649A 1976-05-25 Harold K. Forsen
Method and apparatus for generating and accelerating ions in a vapor by use of relatively polarized laser radiation and a magnetic field. As applied to uranium isotope enrichment, a flowing uranium vapor has particles of the U.sub.235 isotope type selectively ionized by laser radiation and the ionized flow is subjected to a transverse gradient in a magnetic field. The magnetic field gradient induces an acceleration on the ionized particles of U.sub.235 which deflects them from their normal flow path toward a collecting structure. High magnetic field and corresponding high ion accelerations are achieved without loss in ionization selectivity by maintaining a polarization between the applied laser radiation and magnetic field which minimizes Zeeman splitting of the uranium energy states.
