Purcell enhancement and focusing effects in plasmonic nanoantenna arrays (2015)
Journal Article
Stokes, J. L., Sarua, A., Pugh, J. R., Dorh, N., Munns, J. W., Bassindale, P. G., …Cryan, M. J. (2015). Purcell enhancement and focusing effects in plasmonic nanoantenna arrays. Journal of the Optical Society of America B, 32(10), 2158-2163. doi:10.1364/JOSAB.32.002158

This paper presents measured fluorescence results for PMMA dye-coated 5×5 gold plasmonic nanoantenna arrays. We use numerical electromagnetic modeling to show how array size and element spacing can be used to control emitted beam shape and compare th... Read More

Solar absorbers using 1D and 2D periodic nanostructured nickel films (2014)
Journal Article
Ahmad, N., Stokes, J., & Cryan, M. J. (2014). Solar absorbers using 1D and 2D periodic nanostructured nickel films. Journal of Optics, 16(12), doi:10.1088/2040-8978/16/12/125003

This paper presents results obtained from finite difference time domain and transfer matrix method modelling of nickel thin films. It is shown that by adding a periodic 1D grating to the surface of the nickel its optical absorption over the 300 nm–10... Read More
