  1. New paper on influence of disorder on beetle colour

    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.

  2. Deconstructing beetles elucidates origins of colour

    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. […]

  3. New paper on polarisation-insensitive, scalable plasmonic colouration

    Faris Shahidan has led new work appearing today in Optics Express. Using nanoimprint lithography we show that it is possible to generate vivid colouration without the requirement for polarised light. Embossed polymers are coated with a variety of metals permitting an investigation of the role of the choice of metal. This work opens up the […]
