(a) Schematic of the Ge/Mo/C/Mo/Ge waveguide and the X-ray beam filtering. We have investigated different guiding layer thicknesses d of the C layer in the experiments. Profiles of the real δ (b) and the imaginary β (c) part of the refractive index n = 1 + [\delta] − [i\beta] of the multilayer waveguide calculated for energies between 12.0 keV and 18.0 keV. The transmission efficiency of the two-component waveguide is enhanced owing to the relatively high [\delta_{{\rm{Mo}}}] but low [\beta_{{\rm{Mo}}}] of the Mo interlayer.
