Physics and Design Possibilities of Plasmonic-based Fishnet Metamaterial Structures
Result description
Metamaterials (MM) represent a class of artificially-made structures, exhibiting negative values of effective permittivity and permeability in specific spectral regions simultaneously. Recently, such structures haveattracted much attention due to their unique behavior not found in nature. These structures offer, e.g. a possibility of realization of perfect lenses, with spatial resolution below the wavelength limit. We have focused on theoretical rigorous study on one specific class of MM structures, called fishnets, consisting of a combination of metal and dielectric layers with periodically arranged sub-wavelength holes. Our attempt was to reveal the physics and optimize the fishnet structure by tailoring the geometrical features in order to achieve optimized response in terms of negative refraction indices in particular spectral regions. For that purpose, our 2D rigorous coupled wave analysis software was used for computing, the results of which were post-processed in order to retrie
