Caracterización y optimización de resonancias plasmónicas en sistemas multicapas

Abstract

Surface Plasmons (PS) are collective oscillations of free electrons of a metal, also called oscillations of plasma density. These oscillations are strongly confined to the surface and are associated with an evanescent electromagnetic wave. These properties are related to an exceptional increase in the amplitude of the electric field. This work includes a series of studies in which systematically the structure parameters of a multilayer system are controlled to characterize plasmonic resonances. The results allow to identify the excitation of different plasmonic modes that derive a controllable effective optical response, with application potential to the design of materials.
