Reconfigurable microfluidics [PDF]
Nature Reviews Chemistry, 2021 Lab-on-a-chip devices leverage microfluidic technologies to enable chemical and biological processes at small scales. However, existing microfluidic channel networks are typically designed for the implementation of a single function or a well-defined protocol and do not allow the flexibility and real-time experimental decision-making essential to many ...

Thermally reconfigurable metalens
Nanophotonics, 2022 Abstract Reconfigurable metalenses are compact optical components composed by arrays of meta-atoms that offer unique opportunities for advanced optical systems, from microscopy to augmented reality platforms. Although poorly explored in the context of reconfigurable metalenses, thermo-optical effects in resonant silicon nanoresonators ...

Rayleigh Fading Modeling and Channel Hardening for Reconfigurable Intelligent Surfaces [PDF]
IEEE Wireless Communications Letters, 2020 A realistic performance assessment of any wireless technology requires the use of a channel model that reflects its main characteristics. The independent and identically distributed Rayleigh fading channel model has been (and still is) the basis of most ...

Reconfigurable Photonic Metamaterials [PDF]
Nano Letters, 2011 We introduce mechanically reconfigurable photonic metamaterials (RPMs) as a flexible platform for realizing metamaterial devices with reversible and large-range tunable characteristics in the optical part of the spectrum. Here we illustrate this concept for a temperature-driven RPM exhibiting reversible relative transmission changes of up to 50%.

Mechanochromic Reconfigurable Metasurfaces [PDF]
Advanced Science, 2019 AbstractThe change of optical properties that some usually natural compounds or polymeric materials show upon the application of external stress is named mechanochromism. Herein, an artificial nanomechanical metasurface formed by a subwavelength nanowire array made of molybdenum disulfide, molybdenum oxide, and silicon nitride changes color upon ...
