Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
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.

Shedding new light on the Crab with polarized X-rays

Scientific Reports, 2017
Strong magnetic fields, synchrotron emission, and Compton scattering are omnipresent in compact celestial X-ray sources. Emissions in the X-ray energy band are consequently expected to be linearly polarized. X-ray polarimetry provides a unique diagnostic
