Two Scale FE‐FFT‐Based Modeling of Cancellous Bone
ABSTRACT Osteoporosis is characterized by a loss of volume percentage of cortical bone, which reduces the loading capacity of this organ and increases its likelihood for fractures. The disease has the highest prevalence of any bone disease worldwide, with a particularly high incidence among the elderly.

An ab initio electromagnetic framework links quasinormal modes to Fano resonances in extinction spectra. Analytical expressions for the Fano asymmetry and intensity parameters are derived from overlap integrals, enabling rapid spectral reconstruction and physical interpretation.

Interaction of Structured Light With Nanostructured Matter
Structured light–matter interactions at the nanoscale remain poorly understood. We reveal a symmetry‐matched mechanism governing orbital‐angular‐momentum‐dependent extinction in gold nanodisk oligomers. Tailored diffractive optical elements generate flower‐like beams whose rotational symmetry dictates absorption. Experiments and a semi‐analytical model

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging
This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...
