Abstract
An X-ray waveguide according to the present invention includes: a core for guiding an X-ray in such a wavelength band that a real part of the refractive index of a material is 1 or less; and a cladding for confining the X-ray in the core, wherein: the cladding has a periodic structure in which multiple materials having different real parts of the refractive index are periodically arranged in two-dimensional directions perpendicular to the guiding direction of X-ray; and the periodic structure has a period of 100 nm or less.
Claims11
An X-ray waveguide, comprising:
- a core, of a first material, for guiding X-rays in such a wavelength band that a real part of the refractive index of said first material is 1 or less;
- and
- a cladding for confining the X-rays in said core,
- wherein
- said cladding has a periodic structure in which multiple materials, real parts of whose refractive indices are different from each other, are periodically arranged in two-dimensional directions perpendicular to the guiding direction of X-rays, and
- said periodic structure has a period of 100 nm or less,
- wherein said periodic structure includes a mesostructured material formed of said multiple materials.
An X-ray waveguide, comprising:
- a core for guiding X-rays;
- and
- two claddings for confining the X-rays in said core,
- wherein at least one of said claddings comprises mesostructure including (a) a host material having pores formed therein, and (b) materials having a different refractive index from that of said host material in said pores, and
- said pores are periodically arranged in two- or three-dimensional directions with a period of 100 nm or less.
