Semiconductor-based superlens for sub-wavelength resolution below the dif-fraction limit at extreme ultraviolet frequencies
M. A. Vincenti, A. D Orazio, M. G. Cappeddu +3
We theoretically demonstrate negative refraction and sub-wavelength resolution below the diffraction limit in the UV and extreme UV ranges using semiconductors. The metal-like re-s…
Energy considerations for a superlens based on metal/dielectric multilayers
Mark Bloemer, Giuseppe D'Aguanno, Michael Scalora +2
We investigate the resolution and absorption losses of a Ag/GaP multilayer superlens. For a fixed source to image distance the resolution is independent of the position of the lens…
Homogenization procedure for a metamaterial and local violation of the second principle of thermodynamics
Nadia Mattiucci, Giuseppe D'Aguanno, Neset Akozbek +2
Classical theory of crystals states that a medium to be considered homogeneous must satisfy the following requirements: a) the dimension of the elementary cell must be much smaller…
On the Inhibition of Linear Absorption in Opaque Materials Using Phase-Locked Harmonic Generation
Marco Centini, Vito Roppo, Eugenio Fazio +7
We theoretically predict and experimentally demonstrate inhibition of linear absorption for phase and group velocity mismatched second and third harmonic generation in strongly abs…
Anomalous Momentum States, Non-Specular Reflections, and Negative Refraction of Phase-Locked, Second Harmonic Pulses
Vito Roppo, Marco Centini, Domenico de Ceglia +5
We simulate and discuss novel spatio-temporal propagation effects that relate specifically to pulsed, phase-mismatched second harmonic generation in a negative index material havin…
Second harmonic generation from metallo-dielectric multilayer photonic band gap structures
M. C. Larciprete, A. Belardini, M. G. Cappeddu +6
We experimentally and theoretically investigate the second order nonlinear optical response of metallo-dielectric multilayer structures composed of Ag and Ta2O5 layers, deposited b…
