Journal ArticleDOI
Improved analytical fit of gold dispersion: Application to the modeling of extinction spectra with a finite-difference time-domain method
Alexandre Vial,Anne-Sophie Grimault,Demetrio Macías,Dominique Barchiesi,Marc Lamy de la Chapelle +4 more
TL;DR: In this article, an accurate description for the dispersion of gold in the range of 1.24 -2.48 eV was proposed and implemented in an FDTD algorithm and evaluated its efficiency by comparison with an analytical method.
Journal ArticleDOI
A new image encryption scheme based on a chaotic function
TL;DR: The results of several statistical analysis about randomness, sensitivity and correlation of the cipher-images show that the proposed cryptosystem is efficient and secure enough to be used for the image encryption and transmission.
Journal ArticleDOI
Surface enhanced Raman scattering on gold nanowire arrays: Evidence of strong multipolar surface plasmon resonance enhancement
L. Billot,M. Lamy de la Chapelle,Anne-Sophie Grimault,Alexandre Vial,Dominique Barchiesi,Jean-Louis Bijeon,Pierre-Michel Adam,Pascal Royer +7 more
TL;DR: In this paper, the SERS efficiency of gold nanowires arrays elaborated by electron beam lithography and lift-off technique efficiency is investigated by depositing a molecular probe (BPE) trans-1,2-bis(4-pyridyl)ethylen on the arrays and using an excitation wavelength of 632.8 nm.
Journal ArticleDOI
Scanning-tunneling optical microscopy: a theoretical macroscopic approach
TL;DR: In this article, a macroscopic approach is proposed to calculate the intensity detected by a small spherical tip above a regular glass lattice illuminated in total internal reflection, and the model is based on the macroscopy approach for calculating the images obtained in scanning tunneling optical microscopy.
Journal ArticleDOI
Probes for scanning tunneling optical microscopy: a theoretical comparison
TL;DR: In this article, the authors compare theoretical images of the same sample obtained with two different types of probes: a dielectric tip and a small-aperture tip, and show that the two probes do not detect the same information.
