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…
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…
Enhanced Transmission and Second Harmonic Generation from Subwavelength Slits on Metal Substrates
M. A. Vincenti, M. De Sario, V. Petruzzelli +7
We theoretically investigate second harmonic generation that originates from the nonlinear, magnetic Lorentz force term from single and multiple apertures carved on thick, opaque m…
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…
Tailoring Metallodielectric Structures for Super Resolution and Superguiding Applications in the Visible and Near IR Ranges
D. de Ceglia, M. A. Vincenti, M. G. Cappeddu +6
We discuss propagation effects in realistic, transparent, metallo-dielectric photonic band gap structures in the context of negative refraction and super-resolution in the visible…
