Bloch vector analysis in non linear, finite, dissipative systems: an experimental study
G. D'Aguanno, M. C. Larciprete, N. Mattiucci +6
We have investigated and experimentally proved the robustness of the Bloch vector for one-dimensional, nonlinear, finite, dissipative systems. The case studied is the second harmon…
Extraordinary nonlinear optics in ordinary semiconductors
N. Akozbek, V. Roppo, M. A. Vincenti +4
We numerically demonstrate inhibition of absorption, optical transparency, and anomalous momentum states of phase locked harmonic pulses in semiconductors, at UV and extreme UV fre…
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…
Influence of the losses on the super-resolution performances of an impedance matched negative index material
Giuseppe D'Aguanno, Nadia Mattiucci, Mark J. Bloemer
We discuss by a Poynting vector analysis how the losses of a negative index material (NIM) affect the resolution performances of a Veselago-Pendry lens and we analyze those perform…
Ultra-slow light pulses in a nonlinear metamaterial
Giuseppe D'Aguanno, Nadia Mattiucci, Mark J. Bloemer
We find the analytical expression for the threshold intensity necessary to launch ultra-slow light pulses in a metamaterial with simultaneous cubic electric and magnetic nonlineari…
