Influence of light incidence angle and polarization on the refractive index sensitivity of tightly-packed ellipsoidal gold nanoparticle layers

Sensing and Bio-Sensing Research
The effect of excitation angle and polarization on the bulk refractive index sensitivity (RIS) of hexagonally-arranged gold nanoparticles is studied through numerical simulations and experiments.

Radar backscatter properties of milo and soybeans [PDF]

The radar backscatter from fields of milo and soybeans was measured with a ground based radar as a function of frequency (8-18 GHz), polarization (HH and VV) and angle of incidence (0 deg-70 deg) during the summer of 1974.

Strichartz estimates and global well-posedness of the cubic NLS on $\mathbb {T}^{2}$

Forum of Mathematics, Pi
The optimal $L^4$ -Strichartz estimate for the Schrödinger equation on the two-dimensional rational torus $\mathbb {T}^2$ is proved, which improves an estimate of Bourgain. A new method based on incidence geometry is used.

Finite Geometries: a tool for better understanding of Euclidean Geometry

Science & Philosophy, 2014
An effective tool to really understand Euclidean geometry is the study of alternative models and their applications. In fact, they allow you to understand the real extent of various axioms that, when viewed from the Euclidean geometry, seem obvious or ...

Algebraic geometry techniques in incidence geometry

, 2019
Inzidenzgeometrie untersucht das Verhalten endlicher Mengen von Objekten -- Punkten, Geraden, oder Kreisen -- bezüglich geometrischer Operationen wie Kolinearität, Durchschnitt oder Abstand. Arithmetische Kombinatorik untersucht das Verhalten endlicher Teilmengen von Gruppen oder Ringen bezüglich der arithmetischen Operationen, zum Beispiel Addition ...
