Bourlier C, Pinel N, Kubické G.
PMID: 24323253
J Opt Soc Am A Opt Image Sci Vis. 2013 Sep 01;30(9):1727-37. doi: 10.1364/JOSAA.30.001727.

In this article, the fields scattered by coated cylinders, a rough layer, and an object below a rough surface are computed by the efficient propagation-inside-layer-expansion (PILE) method combined with the physical optics (PO) approximation to accelerate the calculation of...

SrRuO3 films and SrRuO3/SrTiO3 superlattices grown on SrTiO3(001) were studied by structural, magnetic, magnetoresistance and Hall effect measurements. The superlattices showed heteroepitaxial growth with coherent interfaces and a Ru/Ti diffusion region of 1-1.5 unit cells. The resistivity had metallic...

Nanotechnology. 2006 May 28;17(10):2518-22. doi: 10.1088/0957-4484/17/10/013. Epub 2006 Apr 24.

The formation of nanocolumns of C clusters in thin films of a Si based inorganic polymer, allylhydridopolycarbosilane (HPCS), as a result of irradiation of the films with 100 MeV Au ions at fluences of 2 × 10(12) and 5...

Sources of variance of downwelling irradiance in water.

Applied optics

Gege P, Pinnel N.

Appl Opt. 2011 May 20;50(15):2192-203. doi: 10.1364/AO.50.002192.

The downwelling irradiance in water is highly variable due to the focusing and defocusing of sunlight and skylight by the wave-modulated water surface. While the time scales and intensity variations caused by wave focusing are well studied, little is...

Tailoring magnetic interlayer coupling in La0.7Sr0.3MnO3/SrRuO3 superlattices.

Physical review letters

Ziese M, Vrejoiu I, Pippel E, Esquinazi P, Hesse D, Etz C, Henk J, Ernst A, Maznichenko IV, Hergert W, Mertig I.
PMID: 20482078
Phys Rev Lett. 2010 Apr 23;104(16):167203. doi: 10.1103/PhysRevLett.104.167203. Epub 2010 Apr 21.

The magnetic interlayer coupling in La0.7Sr0.3MnO3/SrRuO3 superlattices was investigated. High quality superlattices with ultrathin La0.7Sr0.3MnO3 and SrRuO3 layers were fabricated by pulsed laser deposition. The superlattices grew coherently with Mn/Ru intermixing restricted to about one interfacial monolayer. Strong antiferromagnetic...

Shamey R, Shepherd S, Abed M, Chargualaf M, Garner N, Dippel N, Weisner N, Kuehni RG.
PMID: 21979500
J Opt Soc Am A Opt Image Sci Vis. 2011 Oct 01;28(10):1962-9. doi: 10.1364/JOSAA.28.001962.

The aim of this study was to determine how accurately color-normal subjects that have received basic information about, but do not have practical experience with, the Natural Color System (NCS) can estimate the Heringian components of a representative selection...

Energy conservation of the scattering from one-dimensional random rough surfaces in the high-frequency limit.

Optics letters

Pinel N, Bourlier C, Saillard J.
PMID: 16092248
Opt Lett. 2005 Aug 01;30(15):2007-9. doi: 10.1364/ol.30.002007.

Energy conservation of the scattering from one-dimensional strongly rough dielectric surfaces is investigated using the Kirchhoff approximation with single reflection and by taking the shadowing phenomenon into account, both in reflection and transmission. In addition, because no shadowing function...

Energy flow in light-coupling masks for lensless optical lithography.

Optics express

PMID: 19384370
Opt Express. 1998 Sep 28;3(7):280-5. doi: 10.1364/oe.3.000280.

We illustrate the propagation of light in a new type of coupling mask for lensless optical lithography. Our investigation shows how the different elements comprising such masks contribute to the definition of an optical path that allows the exposure...
