Ours is the first rigorous derivation of ray optics equations which include all sub-leading order terms, some of which are also new to the physics literature. While the ray optics limit we prove initially (Theorem 3.3) applies to photonic crystals of any topological class, we also consider ...

diffraction stems from the fact that diffraction from an array of lattice points is equivalent to reflection from these planes. Each set of planes (hkl) leads to one possible diffraction maximum at a diffraction angleθ(theta) defined byBragg'slaw, the derivation of which is shown inFigure 3....
The next step in the derivation is to allow the source and the detector to have finite sizes too, described by small vectors \({\textbf{s}}\) and \({\textbf{d}}\) pointing away from their respective centers (the circles in Fig. 7). In other words, an arbitrary off-center scatterin...
The purple line, derived from the oversampling condition, is elaborated in the Derivation of resolution limit section in Methods. As shown in Eq. (16), it provides the lower bound of L1. Unlike the other two criteria, this is a fundamental criterion that is irrelevant to practical sampling ...

Material-selective analysis of spectral X-ray imaging data requires prior knowledge of the energy dependence of the observed signal. Contrary to conventional X-ray imaging, where the material-specific attenuation coefficient is usually precisely known, t
