Plasmonics is an emergent area of the nanophotonics that studies interaction between electromagnetic fields and free electrons in a metal on a metal/dielectric interface. Due to this interaction, the called surface plasmon ...

The dispersive characteristics of surface plasmon polaritons (SPPs) supported by a periodically corrugated boundary between vacuum and a negative refractive index, isotropic material were studied theoretically by numerical ...

In this work we propose a new approach for the design of resonant structures aiming at wavelength filtering applications. The structure consists of a subwavelength metal-insulator-metal (MIM) waveguide presenting cascaded ...

Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs ...

En este trabajo estudiamos los modos colectivos de una multicapa periódica (superred) del tipo AB, donde A es un material dieléctrico convencional y B un metamaterial magnético. Mostramos que la inclusión de metamateriales ...

Gold plasmonic lenses consisting of a planar concentric rings-groove with different periods were milled with a focused gallium ion beam on a gold thin film deposited onto an Er3+-doped tellurite glass. The plasmonic lenses ...

In this thesis we describe the fabrication of two-dimensional materialheterostructures for the study of structural and optical properties. Our results show that it is possible to build heterostructures with well-defined ...
