摘要： PROBLEM TO BE SOLVED: To provide an optical reflection element having a minute angle of incidence for irradiation of an X-ray wavelength band and particles, to provide a method for manufacturing the optical reflection element, and to provide an optical apparatus equipped with the optical reflection element.
SOLUTION: Regarding the optical reflection element for light beams such as X ray, γray, or high-energy particle ray made incident at a minute angle, the element is provided with at least two silicon plates in a overlapping state forming a laminated structure. Each plate is provided with a 1st upper surface covered with a metal film and a multi-layered or diffused grating so as to reflect the light, and a 2nd surface arranged together with a plurality of ribs functioning as a spacer between the two continuously arranged reflection surfaces so as to define a prescribed interval between the two continuously arranged reflection surfaces. Besides, the optical apparatus is provided with the aforesaid optical element, and the optical apparatus constitutes a type 1 Walter telescope where two parabolic and hyperbolic mirrors of the rotating body are arranged in a column or the conic approximation of the Walter telescope or a Kirkpatrick-Baez type system.

摘要： A broadband satellite antenna for producing a dual-band multiple beam coverage in transmission and reception based on an offset dual-optics configuration that includes a single main parabolic reflector, a hyperbolic sub-reflector, a first transmitting Multiple-Feed-per-Beam feed system, and a second receiving Multiple-Feed-per-Beam feed system. The sub-reflector surface is a Frequency Selective Surface configured to transmit any electromagnetic signals in the higher frequency band and to reflect any electromagnetic signals in the lower frequency band. The Multiple-Feed-per-Beam feed systems are located at the main focal point FMO and at the first sub-reflector real focal point FSreal. The eccentricity e of the hyperbolic sub-reflector depends on a ratio between a preset lower frequency fL in the lower frequency band BL and a preset higher frequency fH in the higher frequency band BH. The first transmitting Multiple-Feed-per-Beam feed system and the second receiving Multiple-Feed-per-Beam feed system are geometrical scaled versions of each other.

摘要： A method of providing multi-beam coverage of a Region of Interest (ROI) in a multi-beam satellite communication system in which a non-uniform traffic demand density is defined over said Region of Interest, the method including partitioning the Region of Interest into N>1 non-overlapping cells (V1-V10, Vi); and generating N satellite beams, each of the satellite beams providing coverage of a respective cell. The step of partitioning the Region of Interest into N>1 non-overlapping cells is performed in such a way that the traffic demand associated to the cells is substantially uniform. Advantageously, the cells form a Voronoi diagram defined over the Region of Interest, the satellite beams being pointed towards the cells of the Voronoi diagram. A satellite communication system implementing the method is also provided.

摘要： According to the invention, a nullGenevanull movement mechanism is used which is turned in one direction or the other by an electric motor. The mechanism comprises a nullMaltesenull cross turning about the axis of rotation of the rotor and supporting an annular piece. The Maltese cross is mechanically coupled to a ball screw lying on said axis of rotation so as to transform the turning notion into motion that includes a linear component, thereby enabling the annular piece to be moved at will towards and away from the rotor so as to make it possible to obtain contact and then blocking in a self-blocking manner against a fixed wall, or on the contrary so as to release the rotor by moving the annular piece in translation in the opposite direction. The invention is applicable to an inertia wheel for controlling the attitude of a satellite.
