Angularly Stable Terahertz Metasurface With Multi‐Frequency Narrowband Cross‐Polarization Conversion and Broadband Quarter Waveplate Function

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
A compact dual‐functional reflective terahertz (THz) metasurface is experimentally demonstrated. Near‐unity linear‐to‐cross polarization conversion is achieved at four resonance frequencies: 0.65, 0.80, 2.02, and 2.48 THz. Broadband linear‐to‐circular polarization conversion is realized in two bands, 0.86–1.95 THz (77% fractional bandwith, FBW) and 2 ...

The Interplay of Magnetic Order with the Electronic Scattering and Crystal‐Field Effects in a Metallic Ferromagnet

Advanced Science, Volume 13, Issue 13, 3 March 2026.
The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Terahertz Spectroscopy on Pyrite

Pyrite is identifiable. The Iron (II) disulfide [FeS2] structure becomes isoclinic with minimal tetragonal [CuFeS2], orthorhombic [FeS2], or monoclinic [AsFeS2] forms. Physical examination validates crystal structure and composition. A tetragonal, pale brassy yellow, 6.0 Moh’s hardness, indistinct cleavage, 4.68 g/cm3 specific gravity, metallic luster,

Rod‐Like PLGA Microrobots with Enhanced Motion and Biodegradation for Magnetic‐Guided Drug Delivery

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This study presents drug‐loaded Poly (lactic‐co‐glycolic acid) (PLGA) microrobots fabricated from an oil‐in‐water (O/W) emulsion of PLGA, Fe3O4 nanoparticles, and Adriamycin (DOX). They are formed by film‐forming and stretching microrobots, and exhibit motion analyzed via video‐snapshots, speed graphs, and shape changes, advancing targeted for drug ...
