Surface plasmon drag effect in a dielectrically modulated metallic thin film

Giant Surface-Plasmon-Induced Drag Effect (SPIDEr) in Metal Nanowires

Giant surface-plasmon-induced drag effect in metal nanowires.

Here, for the first time we predict a giant surface-plasmon-induced drag-effect rectification (SPIDER), which exists under conditions of the extreme nanoplasmonic confinement. In nanowires, this giant SPIDER generates rectified THz potential differences up to 10 V and extremely strong electric fields up to approximately 10(5)-10(6) V/cm. The giant SPIDER is an ultrafast effect whose bandwidth f...

Surface Plasmon Resonance Sensor with Magneto-optical Thin Film

Thanks to resonant excitation of surface plasmons, SPR sensors including ferromagnetic thin films allow the enhancement of the magneto-optical response. MO-SPR structures with Au/Co/Au sandwiches are theoretically analyzed in transverse configuration. The influence of sandwich film thicknesses and layer order is discussed. The optimized geometry and corresponding feedback are specified.

Antibonding plasmon mode coupling of an individual hole in a thin metallic film

The polarization dependence of the optical properties of individual subwavelength holes in a thin metallic film is studied using terahertz time-domain spectroscopy. We show that for parallel polarization of the incident light, the coupling is predominantly to short-range bonding film plasmons while for perpendicular polarization the incident light couples more efficiently to long-range antibond...

Metallic film optimization in a surface plasmon resonance biosensor by the extended Rouard method.

The extended Rouard method is applied to the computation of a multi-absorbing-layer system for the optimization of surface plasmon resonance (SPR) sensors. Specifically, the effect of the properties of a metallic layer on the shape of the reflectivity and sensitivity curve is demonstrated in the case of a Kretschmann configuration. This theoretical investigation allows us to establish the best ...
