Figure 4
Comparison between the measured waveguide transmission (dots, the dashed line connects the points as a guide for the eye) and the predicted transmission according to (16)[link] or (17)[link] (solid line) depending on photon energy for two waveguides with Be cores sandwiched between Mo layers. The cover layers have thicknesses of d1 = 5.5 nm, while the core thicknesses are d2 = 74 nm in (a) and d2 = 110 nm in (b). The transmission coefficients in (a) and (b) are different as the beam aperture was opened from 50 µm (a) to 100 µm (b).
