Two-peaked and flat-top perfect bright solitons in epsilon-near-zero nonlinear metamaterials: novel Kerr self-trapping mechanisms
Alessandro Ciattoni, Carlo Rizza, Elia Palange
We analytically investigate transverse magnetic (TM) spatial bright solitons, as exact solutions of Maxwell's equations, propagating through nonlinear metamaterials whose linear di…
Photonic Crystals with Controlled Disorder
P. D. Garcia, R. Sapienza, C. Toninelli +2
Photonic crystals are extremely sensitive to structural disorder even to the point of completely losing their functionalities. While on one side this can be detrimental for applica…
Molecular imaging with X-ray free electron lasers: dream or reality?
Andrea Fratalocchi, Giancarlo Ruocco
X-ray Free Electron Lasers (XFEL) are revolutionary photons sources, whose ultrashort, brilliant pulses are expected to allow single molecule diffraction experiments providing stru…
Multistability at arbitrary low optical intensities in a metallo-dielectric layered structure
Alessandro Ciattoni, Carlo Rizza, Elia Palange
We show that a nonlinear metallo-dielectric layered slab of subwavelength thickness and very small average dielectric permittivity displays optical multistable behavior at arbitrar…
Propagation of Bessel beams from a dielectric to a conducting medium
D. Mugnai
Recently, the use of Bessel beams in evaluating the possibility of using them for a new generation of GPR (ground penetrating radar) systems has been considered. Therefore, an anal…
Transmissivity directional hysteresis of a nonlinear metamaterial slab with very small linear permittivity
Alessandro Ciattoni, Carlo Rizza, Elia Palange
We investigate propagation of a transverse magnetic field through a nonlinear metamaterial slab of sub-wavelength thickness and with a very small and negative linear dielectric per…
