AI Summary (NQ-processed)
A research team from Chiba University, Tohoku University, and the National Institute for Materials Science (NIMS) has developed a new spectroscopic imaging technology that uses a 'moiré metasurface' of stacked silver micro-disks to directly observe the spatial distribution of right- and left-handed chirality in materials as 2D images using terahertz (THz) waves. For the first time globally, they succeeded in visualizing a mixture of different chiralities, which was impossible with conventional averaging measurements. The results were published in the journal ACS Photonics on June 2, 2026, and are expected to be applied in quality evaluation of next-generation materials, biomolecular structure analysis, and 6G communication device development.
