Theoretical calculation of finite-temperature X-ray absorption fine structure: application to sodium K-edge in NaCl
Philipp Hönicke, Yves Kayser, Pouya Partovi-Azar
We present a comprehensive computational framework for reproducing the full X-ray absorption fine structure (XAFS) through quantum-chemical simulations. The near-edge region is acc…

Polygon-based unified Fourier-modal approach for diffractive optics simulations
K. V. Nikolaev, V. Soltwisch, M. A. Botchev +4
In this article, we derive a theoretical formalism that unifies the rigorous coupled wave analysis and the dynamical diffraction theory. Based on this formalism, we design a comput…
