Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering (Advanced Optical Materials 1/2026)
Laser-Engineered Thermal Metamaterial Platforms In the Research Article (DOI: 10.1002/adom.202502035), Ufuk Kilic, Mohammad Ghashami, and co-workers present a metamaterial platform based on femtosecond laser surface processing (FLSP) of titanium surfaces. By tuning laser fluence and pulse count, self-organized Ti–TiOx core–shell mound structures are generated, whose emissivity can be precisely tailored by structural parameters. Combining Mueller matrix spectroscopic ellipsometry and finite element modeling, the study reveals how the engineered structures govern near- and far-field characteristics, activating plasmonic and interband resonance modes across UV to mid-IR wavelengths.
