Terahertz Chiral Recognition Based on Metasurfaces
A novel terahertz chiral sensing method based on a multilayer metallic metasurface is proposed. The left‐handed circularly polarized and right‐handed circularly polarized components in the linearly polarized illuminating light into two focal points and convert them back into linear polarization for convenient measurement.

Acoustic Sensing as a Tool for Brain Tumor Diagnostics
Surface acoustic wave (SAW) sensing is used to distinguish non‐neoplastic brain tissue from primary and metastatic tumors based on their acoustic attenuation signatures. Ex vivo human brain samples reveal clear tissue‐specific mechanical profiles, correlating with stiffness and malignancy.

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals
Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...
