Far-infrared graphene plasmonic crystals for plasmonic band engineering.
We introduce far-infrared graphene plasmonic crystals. Periodic structural perturbation-in a proof-of-concept form of hexagonal lattice of apertures-of a continuous graphene medium alters delocalized plasmonic dynamics, creating plasmonic bands in a manner akin to photonic crystals. Fourier transform infrared spectroscopy demonstrates band formation, where far-infrared irradiation excites a uni...
متن کاملBand Gaps of Diamond Structured Photonic Crystals
In a three dimensional photonic crystal, an artificially formed dielectric structure, periodic along three different axes, when electromagnetic waves interact they periodically modulate the dielectric constant. A photonic band gap may form in these directions prohibiting the propagation of photons for energies that lie within the gap. Under certain conditions, there will be regions of forbidden...

متن کاملPlasmonic band gaps and trapped plasmons on nanostructured metal surfaces.
Nanostructured metal surfaces comprised of periodically arranged spherical voids are grown by electrochemical deposition through a self-assembled template. Detailed measurements of the angle- and orientation-dependent reflectivity reveal the spectral dispersion, from which we identify the presence of both delocalized Bragg and localized Mie plasmons. These couple strongly producing bonding and ...
