High‐Aspect‐Ratio Nanostructured Surfaces as Biological Metamaterials [PDF]
Advanced Materials, 2020 AbstractMaterials patterned with high‐aspect‐ratio nanostructures have features on similar length scales to cellular components. These surfaces are an extreme topography on the cellular level and have become useful tools for perturbing and sensing the cellular environment. Motivation comes from the ability of high‐aspect‐ratio nanostructures to deliver

A High Aspect Ratio Inverse-Designed Holey Metalens.
Nano letters (Print), 2021 Free-standing nanofins or pillar meta-atoms are the most common constituent building blocks in metalenses and metasurfaces in general. Here, we present an alternative metasurface geometry based on high aspect ratio via-holes.

International Journal of Extreme Manufacturing, 2022 We report novel results on top-down percussion drilling in different glasses with femtosecond laser GHz-bursts. Thanks to this particular regime of light–matter interaction, combining non-linear absorption and thermal cumulative effects, we obtained ...
