In work just published in Nature Communications, a collaboration between University of Melbourne, CUNY, and RMIT University has demonstrated a metasurface that can be switched between edge detection and producing a conventional image. The device integrates a thin film of VO2 that undergoes a phase change at around 68C altering its optical properties opening up […]

In work led by McKenzie Fellow, Dr Nitu Syed, researchers from the ARC Centre of Excellence for Transformative Meta-Optical Systems, have developed a gas sensor using atomically thin transparent two-dimensional (2D) tin dioxide film. The material has a thickness of only 2 nanometres which is 50000 times thinner than a paper. Reducing the thickness to […]

Work led by Tim Davis is featured as an Editor’s Pick in the latest Optics Express – link here. We show that by extracting structural information from transmission electron microscopy data, including characteristic disorder parameters, good agreement with spectral specular and non-specular reflectance measurements can be obtained.

In work just published in Materials Today Advances, members of the group, led by Laura Ospina-Rozo, report new results into the optical and near-infrared properties of beetle elytra. We showed that some scarab beetles use composite, non-chiral structures to reflect light where the elytra consist of a broadband reflective structure overlain by a green filter. […]
