AN INCIDENCE CONJECTURE OF BOURGAIN OVER FIELDS OF POSITIVE CHARACTERISTIC
Forum of Mathematics, Sigma, 2016 In this note we generalize a recent theorem of Guth and Katz on incidences between points and lines in 3-space from characteristic 0 to characteristic $p ...

Theoretical model for the transmittance in a left-handed metamaterial of different geometries [PDF]
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2023 In this work, a theoretical model for the transmittance in a left-handed metamaterial of different geometries is presented. The proposed unit cells are a combination of conducting wires of rectangular cross-section with square-ring and hexagonal ...

High efficiency near diffraction-limited mid-infrared flat lenses based on metasurface reflectarrays [PDF]
, 2016 A limiting factor in the development of mid-infrared optics is the lack of abundant materials that are transparent, low cost, lightweight, and easy to machine. In this paper, we demonstrate a metasurface device that circumvents these limitations.

Polynomial effective equidistribution
Comptes Rendus. Mathématique, 2023 We prove effective equidistribution theorems, with polynomial error rate, for orbits of the unipotent subgroups of $\mathrm{SL}_2(\mathfrak{l})$ in arithmetic quotients of $\mathrm{SL}_2(\mathbb{C})$ and $\mathrm{SL}_2(\mathfrak{l})\times \mathrm{SL}_2 ...

Method for fast determination of the angle of ionizing radiation incidence from data measured by a Timepix3 detector [PDF]
Journal of Sensors and Sensor Systems, 2021 This paper presents a method of how to determine spatial angles of ionizing radiation incidence quickly, using a Timepix3 detector. This work focuses on the dosimetric applications where detectors and measured quantities show significant angle ...

Point-curve incidences in the complex plane [PDF]
, 2017 We prove an incidence theorem for points and curves in the complex plane. Given a set of $m$ points in ${\mathbb R}^2$ and a set of $n$ curves with $k$ degrees of freedom, Pach and Sharir proved that the number of point-curve incidences is $O\big(m ...

Matroid Enumeration for Incidence Geometry [PDF]
Discrete & Computational Geometry, 2011 Matroids are combinatorial abstractions for point configurations and hyperplane arrangements, which are fundamental objects in discrete geometry. Matroids merely encode incidence information of geometric configurations such as collinearity or coplanarity, but they are still enough to describe many problems in discrete geometry, which are called ...

Anisotropic Wavefronts and Laguerre Geometry [PDF]
, 2014 Motivated by the study of wave fronts in anisotropic media, we propose an incidence geometry of anisotropic spheres in a Finsler-Minkowski space. An anisotropic version of the Laguerre functional is considered.

THE FULFILLED EUCLIDEAN PLANE [PDF]
, 2009 The fulfilled euclidean plane is the real projective plane, completed with the infinite point of its infinite line denoted new incidence structure. This is a structure with neighbouring elements, in which the unicity of the line through two distinct ...
