Article Synopsis
- This text discusses a novel method for creating polarization-sensitive plasmonic metasurfaces using pulsed laser light to form periodic surface structures on thin nickel films.
- The resulting metasurface features a unique metal-insulator-metal design with sinusoidal metallic nanowires that can control light polarization in reflection.
- The research demonstrates that by varying the size of the insulating layer, the absorption characteristics can be adapted, leading to high extinction ratios and precise control over light polarization in the near and mid-infrared range.

Article Synopsis
- - The study investigates how varying femtosecond laser parameters, like fluence, energy dose, and interpulse delay, affect the surface patterns created on stainless steel using double pulses.
- - Short interpulse delays (5 ps) favor the formation of low spatial frequency structures, while longer delays (20 ps) promote high spatial frequency patterns, impacting the topography of the material.
- - The research shows a link between surface roughness and wetting properties, as well as cell adhesion responses, highlighting the potential for creating custom surfaces for functional implants.
