We propose to use silver/gold sandwich structures to combine the advantages of silver and gold - two materials of choice for nanoplasmonics and metamaterials. We report on the preparation, characterization, and theoretical modeling of the proposed system.
Plasmonic metamaterials provide a convenient experimental platform for demonstration of principles of transformation optics. Results of imaging experiments using plasmonic metamaterials have been confronted with numerical simulations.
The feasibility of realizing an active Tera Hertz (THz) switch by utilizing artificially corrugated perfect conductor meta-materials is reported in this paper by demonstrating that the strongly localized THz spoof surface plasmon polariton (SSPP) modes can be easily controlled by changing the refractive index of dielectrics inside a longitudinal metallic structure with a periodic array of grooves...
We report on experimental realization of different metal-dielectric structures that are used as surface plasmon polariton waveguides and as plasmonic metamaterials. Fabrication approaches based on different lithographic and deposition techniques are discussed.
Surface plasmon polaritons (SPPs) are elementary electromagnetic (EM) excitations bounded at a metal/dielectric interface. Due to two important features - local field enhancement and subwavelength resolution capability - of the SPP, it has attracted considerable attention recently and many SPP-based applications were proposed or demonstrated. However, for a natural material, its plasmon frequency...
