Plasmonic simulation

Surface plasmon resonances continue to be of great interest in both theoretical research and experimental work on plasmonic structures, or systems that often include nanostructured metallic components. This is because surface plasmons may collect, concentrate, and spread optical energy. The theoretical foundations and computer modelling of these structures are covered in this Feature Article. Also provided are numerous examples, such as the optical transmission by nanohole arrays in thin metal films, the generation of narrow band plasmons by remote grating, the excitation of dark modes in bipyramidal nanoparticles, optical transparencies in nanoparticle-quantum dot systems, and the size dependence of surface.
