Intereses de investigación primarios
Primary research interests

Our research group (Grupo de Electromagnetismo y Ondas, of which I am the Director) focuses on two active areas of current electromagnetism, nanophotonics and plasmonics. The common objective of research in these areas  is to control the emission and propagation of electromagnetic radiation through  structured materials, obtained by  combining two or more phases of a same material or different materials as well. This is of interest in a wide range of applications, including nano-scale guidance and manipulation, bio-detection of low concentrations of molecules, opto-electronic technology for signal transmission and processing, resolution below the optical limit, and control of spontaneous emission and of the energy transfer between molecules mediated by the electromagnetic modes of the structure.

Title: Optical pulling force on dielectric particles via metallic slab surface plasmon excitation: a comparison between transmission and reflection schemes

Authors: H Ferrari, V Herrero, M Cuevas.

Comment: In the Star trek movie, we can see the Enterprise tractor beam doing a fine job of pulling in a shuttle craft, towing another ship, or inhibiting the escape of an enemy spacecraft. By using a thin layer of gold material, in this paper,  we demonstrate the generation of the  tractor beam acting on silice nanoparticles.
