(a) Simulated transmission coefficient for the uniform (non-structured) WG (dashed line) and for the structured WG (solid line) as a function of the effective transverse dimension of the guiding layer. (b) Flux attenuation along the structured waveguide with vacuum gap deff = 241 nm (solid line) corresponding to super-resonance conditions deff = 225 nm (dotted line), deff = 280 nm (dashed line). In the calculation the incident photon energy was Einc = 8 keV, the WG length L = 4 mm and the grating period P = 200 µm. |
