Nanostructures: Aperiodic arrays.

The article reports on the research finding from Boston University in the U. S. that broad plasmonic resonances spanning the entire visible spectrum, can be given rise by two-dimensional arrays of gold nanoparticles which are arranged according to aperiodic mathematical sequences. According to Ashwin Gopinath and colleagues, in creating a range of broadband plasmonic devices, the structures could establish its use.
