Analysis of surface plasmon waves in metaldielectric- metal structures and the criterion for negative refractive index.
Surface plasmon waves in metal-dielectric-metal structures have been theoretically examined. Because of the existence of evanescent waves that can have comparable or smaller decay rates than the propagating waves, the sign of dispersion does not necessarily indicate the sign of effective refractive index for these structures. By using the direction of energy decay to distinguish the sign of ind...
متن کاملDuctility of thin metal films on polymer substrates modulated by interfacial adhesion
When a laminate of a thin metal film on a tough polymer substrate is stretched, the metal film may rupture at strains ranging from a few percent to a few tens of percent. This variation in the ductility of the metal film is modulated by the adhesion of the metal/polymer interface. To study this modulation, here we use the finite element method to simulate the co-evolution of two processes: debo...
متن کاملSurface Properties of Bottlebrush Polymer Thin Films
Bottlebrush polymer thin films may be attractive for the preparation of antifouling and/or stimuli-responsive surface coatings due to the high grafting density and conformational flexibility of polymeric side chains, but bottlebrush polymer thin films have not been previously reported and their surface properties are unknown. Herein, we report a study of the surface properties of mixed bottlebr...

متن کاملSurface plasmon-polariton mediated light emission through thin metal films.
The emission of light by sources in close proximity to a thin metallic film is dominated by surface plasmon-polariton modes supported by that film. We explore the nature of the modes and examine how the energy lost to such modes can be recovered. Both cross-coupled and coupled SPPs are presented as a means of transferring energy across a thin metal film. These modes are then scattered and there...
