Figure 2
Simulated electromagnetic field intensities of the Ge/Mo/C/Mo/Ge waveguide at 15.0 keV [(a) d = 35 nm C layer, (b) d = 18 nm C layer, (c) d = 9 nm C layer] and of the Ge/Ni/C/Ni/Ge waveguide at 8.0 keV [(d) d = 18 nm C layer]. The simulations show two-mode propagation in (a) and mono-modal propagation in (b)–(c). (e)–(h) Simulated near-field distributions in the exit plane corresponding to (a)–(d), respectively. The data show how the exit fields depend on the waveguide length and the guiding layer thickness.
