Shape- and element-sensitive reconstruction of periodic nanostructures with grazing incidence X-ray fluorescence analysis and machine learning
The angular resolved fluorescence signal from a grazing incidence X-ray illumination of periodic nanostructures is used to reconstruct its geometry parameters. The parameter reconstruction using JCMsuite is based on a finite-element model of the scattering and fluorescence process as well as an efficient Bayesian minimization of the disagreement between the simulated and the measured fluorescence signal.

Flat optics in high numerical aperture broadband imaging systems
Integrating diffractive lenses (DLs) into optical imaging systems often significantly decrease their size or increase their performance. Despite only efficient for small diffraction angles, it is quantitavily shown that DLs are suitable for high-numerical-aperture systems. JCMsuite is used to simulate the diffraction properties in the limit of infinitely periodic structures.
