N2lles
N2lles is a fictional class of optical metamaterials introduced in speculative discussions of nano-engineered media. In this conceptual framework, N2lles are designed to exhibit a negative refractive index in the near-infrared, achieved through a carefully arranged layered nano-architecture that couples dielectric and plasmonic responses.
The proposed structure consists of alternating ultra-thin dielectric and metallic nano-layers arranged in a quasi-crystalline lattice.
Fabrication concepts for N2lles rely on advanced thin-film deposition, nanoimprint lithography, or self-assembly techniques capable of
Potential applications discussed include super-resolution imaging, compact waveguides, and novel optical components that manipulate phase fronts.
