Electric Field Enhancement in ε-near-zero Slabs under TM-Polarized Oblique Incidence
Salvatore Campione, Domenico de Ceglia, Maria Antonietta Vincenti +2
We investigate local field enhancement phenomena in subwavelength, ε-near-zero (ENZ) slabs that do not exploit Fabry-Pérot resonances. In particular, we study the linear response o…
Gain assisted harmonic generation in near-zero permittivity metamaterials made of plasmonic nanoshells
Maria Antonietta Vincenti, Salvatore Campione, Domenico de Ceglia +2
We investigate enhanced harmonic generation processes in gain-assisted, near-zero permittivity metamaterials composed of spherical plasmonic nanoshells. We report the presence of n…
Second Harmonic Generation in Deeply Sub-Wavelength Waveguides
V. Roppo, M. A. Vincenti, D. de Ceglia +1
We theoretically investigate second harmonic generation in extremely narrow, sub-wavelength semiconductor and dielectric waveguides. We discuss a novel guiding mechanism characteri…
Raman Scattering near Metal Nanostructures
M. Scalora, M. A. Vincenti, D. de Ceglia +2
We study Raman scattering in active media placed in proximity of different types of metal nanostructures, at wavelengths that display either Fabry-Perot or plasmonic resonances, or…
