A wide variety of sources were consulted and condensed to provide detailed derivations and coverage of the topics of neutron and x-ray optics as well as the background material needed to understand the physical and mathematical reasoning directly related or indirectly related to the theory and ...
Both theoretical derivations with numerical simulation and experiments were performed to confirm the veracity and feasibility of the proposed method. In addition, we present the advantages of the proposed method over the phase-stepping method. Introduction In recent years, X-ray grating-based phase-...
I think I do understand wave optics well enough to understand Bragg's law since I get what textbooks are saying and I'm familiar with the Young's experiment, diffraction on single slit and diffraction grating. I understand conditions of constructive interference and the derivations of intensity ...
This paper's main topic is light transport in anisotropic materials, but the accompanying tech report contains nice derivations of the standard case as well, for the diffusion approximation and the dipole BSSRDF. [Jakob & Marschner 2012] Wenzel Jakob and Steve Marschner. “Manifold exploration: a...
Moreover, numerous quantitative models have been proposed for calculating the emissivity of rough metals based on experimental data and theoretical derivations. Such methods can be categorised into three classes: formula-based methods, direct Maxwell's equation solvers, and methods based on geometric ...
In Appendix A, we provide more detailed derivations of Equation (10). Figure 1. Schematic illustration of the unified optics model: Toroidal VLS grating. Equation (10) can almost reduce to the 𝐊K matrices of all the optical elements in soft XFEL beamline by adjusting the parameters in ...

This difference is explained by the larger EXAFS amplitudes in HR-fluorescence than in transmission or NR-fluorescence, and highlights the importance of using the right acquisition mode to be able to better constrain the S02 parameter and to use it for more accurate derivations of coordination ...
This rule must be taken into account in all fermion propagators, including internal lines such as in the vacuum polarization and in photon splitting processes. The symbols 𝛾𝜇γμ are the Dirac matrices that span the spinorial components of the fermion fields. If the external field is suff...
J.H. performed the calculations for 4U 0142+61 and the derivations in Section 2.1. I.C. performed the calculations for Her X-1. J.H. wrote the bulk of the paper. Funding: This work was supported by a Discovery Grant from the Natural Sciences and Engineering Research Council of Canada,...
