摘要:
A mesostructured film is provided having a structure in which surfactant molecular assemblies are regularly arranged three-dimensionally. A polymer compound thin film is formed on the substrate surface through spin coating or the like, and a rotating roller wrapped with a cloth is pressed against the polymer film for rubbing in one direction. The polymer material includes polyimide, polyamide, and polystyrene. The substrate includes a silica glass substrate and a silicon substrate. The mesostructured film can be formed by retaining the substrate in an aqueous solution containing a surfactant, silicon alkoxide, and acid. After being retained in the solution, the substrate is heated at about 60 to 120° C. for several hours to several days for reaction. The surfactant includes C18H37 (OCH2CH2)200H and C16H33 (OCH2CH2) 200H. The alkoxide included tetraethoxysilane, tetramethoxysilane, and tetrapropoxysilane. Hydrochloric acid, nitric acid, or sulfuric acid is used as a catalyst.

摘要:
A X-ray waveguide includes a core for guiding X-rays having a wavelength band in which the real part of refractive index of material is smaller than 1 and a cladding for confining the X-rays in the core. The core has a one-dimensional periodic structure in which a plurality of layers respectively formed of inorganic materials having different real parts of refractive index are periodically laminated. The core and the cladding are configured so that a critical angle for total reflection for the X-rays at an interface between the core and the cladding is larger than a Bragg angle due to a periodicity of the one-dimensional periodic structure. A critical angle for total reflection for the X-rays at an interface between layers in the one-dimensional periodic structure is smaller than the Bragg angle due to the periodicity of the one-dimensional periodic structure.
摘要:
An X-ray holography light source element divides an entering X-ray beam to emit two or more mutually coherent X-ray beams. The light source element includes an X-ray waveguide which has a core and a cladding. The core contains a plurality of substances different in a refractive-index real part and is a periodic structure body in which basic structures are periodically disposed; the cladding confines an X-ray to the core to be guided therethrough. The total reflection critical angle of the X-ray on the interface of the core and the cladding is larger than the Bragg angle corresponding to the periodicity of the basic structures of the core. A shield member provided with two or more opening portions for respectively emitting the two or more mutually coherent X-ray beams is disposed at the end portion at an emission side of the X-ray waveguide.
