Numerical Investigation into a New Method of Non-Axisymmetric End Wall Contouring for Axial Compressors

open access: yesEnergies, 2022
To deal with corner separation in high-load axial compressors, this paper proposes a new end wall contouring method aimed at controlling the end wall secondary flow in more than one local area, generating a geometry with fewer control variables that is ...

Numerical Investigation of External Electromagnetic Field Coupling to Coplanar Waveguide [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2020
In this paper, for the first time, effects of external electromagnetic fields on a coplanar waveguide (CPW) are numerically studied by means of the method of finite elements. Two CPW lines with different geometry and dielectric substrate permittivity are

Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...

High efficiency near diffraction-limited mid-infrared flat lenses based on metasurface reflectarrays [PDF]

open access: yes, 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.

AN INCIDENCE CONJECTURE OF BOURGAIN OVER FIELDS OF POSITIVE CHARACTERISTIC

open access: yesForum 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]

open access: yesJournal 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 ...

Highly sensitive magnetic field sensor with normal-incidence geometry using Ni-based bilayer subwavelength periodic structure operating in visible-wavelength region

open access: yesJapanese Journal of Applied Physics, 2018
We successfully demonstrate a highly sensitive optical sensor for detecting magnetic fields with normal-incidence geometry that uses a Ni-based bilayer subwavelength periodic structure (SWS) operating in the visible-wavelength region. The electromagnetic

Polynomial effective equidistribution

open access: yesComptes 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 ...
