Giant rotary power of a fishnet-like metamaterial

S.X. Wang, F. Garet, Eric Lheurette, M. Astic, J.L. Coutaz, D. Lippens

We show experimentally and numerically that cholesteric-type metal-dielectric structures, made of twisted sub-wavelength hole elliptical–shaped arrays, exhibit strong optical activity and circular dichroism. The experimental demonstration is carried out with terahertz time-domain spectroscopy…

Enhanced gold film-coupled graphene-based plasmonic nanosensor

Rana Nicolas, Thomas Maurer, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

In this work, a trilayer graphene is used as a thin non dielectric spacer with a high index of refraction, between Au film and Au NPs. Encouraged by the sharpness of the localized surface plasmon resonance LSPR induced by this system, we performed sensitivity measurements to refractive index change…

Open problems in mathematical modelling and physical experiments: exploring exponential function

Raffaele Pisano, Paolo Bussotti

Generally speaking the exponential function has large applications and it is used by many non physicians and non mathematicians, too. Nevertheless some crucial and practical problems happen for its mathematical understanding. Mostly, this part of mathematical cognitive programmes introduce it from…

Theory and Monte Carlo simulations for the stretching of flexible and semiflexible single polymer chains under external fields

F. Manca, S. Giordano, Pier Luca Palla, F. Cleri, L. Colombo

Recent developments of microscopic mechanical experiments allow the manipulation of individual polymer molecules in two main ways: uniform stretching by external forces and non-uniform stretching by external fields. Many results can be thereby obtained for specific kinds of polymers and specific…

Dynamics of confined cavity modes in a phononic crystal slab investigated by in situ time-resolved experiments

R. Marchal, Olga Boyko-Kazymyrenko, Bernard Bonello, Jinfeng Zhao, Laurent Belliard, Mourad Oudich, Yan Pennec, Bahram Djafari-Rouhani

The confinement of elastic waves within a single defect in a phononic crystal slab is investigated both experimentally and theoretically. The structure is formed by a honeycomb lattice of air holes in a silicon plate with one hole missing in its center. The frequencies and polarizations of the…

On the origin of basal stacking faults in nonpolar wurtzite films epitaxially grown on sapphire substrates

Philippe Vennéguès, Jean Michel Chauveau, Z. Bougrioua, Tiankai Zhu, Denis Martin, Nicolas Grandjean

The microstructure of nonpolar heteroepitaxial wurtzite films (GaN and ZnO-based) is dominated by the presence of planar basal stacking faults (BSFs). In this paper, transmission electron microscopy studies of both GaN and ZnO nonpolar films oriented either (11–20) or (1–100) and grown on sapphire…

Microwave On/Off ratio enhancement of GaAs photoconductive switches at nanometer scale

Charlotte Tripon-Canseliet, Salim Faci, Antoine Pagies, Vincent Magnin, Stéphane Formont, Didier Decoster, Jean Chazelas

This paper reports on performances enhancement of photoconductive switches in term of On/Off ratio and insertion losses. The optimization parameters on which the research has been focused are gap dimensions reduction to nanometer scale. The device characterization results up to a microwave…
