OTA testing of near‐field and far‐field communication links
Electronics Letters, 2023 In this work, near‐field and far‐field link measurement in metal enclosure environment is performed. The performance of near‐field and far‐field links are assessed using key performance indicators such as error vector magnitude, bit error rate, and ...

Comparison of image reconstruction by using near-field and far-field data for an imperfect conductor [PDF]
, 2010 Image reconstruction by using near-field and far-field data for an imperfectly conducting cylinder is investigated. A conducting cylinder of unknown shape and conductivity scatters the incident wave in free space and the scattered near and far fields are

Robust Array Diagnosis Against Array Mismatch Using Amplitude-Only Far Field Data
IEEE Access, 2019 This paper presents an array diagnosis method using amplitude-only far-field data robust against array mismatch. The considered array mismatch includes frequency shifting error and element position error.

Far-field intensity signature of sub-wavelength microscopic objects [PDF]
, 2020 Information about microscopic objects with features smaller than the diffraction limit is almost entirely lost in a far-field diffraction image but could be partly recovered with data completition techniques.

Far-field and near-field directionality in acoustic scattering
New Journal of Physics, 2020 Far-field directional scattering and near-field directional coupling from simple sources have recently received great attention in photonics: beyond circularly-polarized dipoles, whose directional coupling to evanescent waves was recently applied to ...

Far-field Noise Prediction of Round and Serrated Jets with Increasingly Refined Grids [PDF]
, 2016 Turbulent jet large-eddy simulations (LES) are performed at Mach 0.9 and Reynolds number of 106. For subgrid scale stress modeling the sigma-model is used.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
