Numerical Study of Non-Schell Model Pulses in Nonlinear Dispersive Media with the Monte Carlo-Based Pseudo-Mode Superposition Method

open access: yesPhotonics
Recently, we introduced random complex and phase screen methods as powerful tools for numerically investigating the evolution of partially coherent pulses (PCPs) in nonlinear dispersive media.

Polarization and coherence for vectorial electromagnetic waves and the ray picture of light propagation [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2007
We develop a complete geometrical picture of paraxial light propagation including coherence phenomena. This approach applies both for scalar and vectorial waves via the introduction of a suitable Wigner function and can be formulated in terms of an ...

SAR Coherence Estimation by Composition of Subsample Estimates and Machine Learning

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) coherence magnitude is an essential parameter in SAR interferometry. This is the reason why current interferometric wide area ground motion services require the estimation of the coherence magnitude as accurately and ...

Disruption of EEG resting state functional connectivity in patients with focal epilepsy

open access: yesThe Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2023
Background Epilepsy is a network disease and EEG could be used to evaluate dynamic inter-regional connectivity. The aim of the current study is to explore disruption of resting state EEG functional connectivity in focal epilepsy using coherence and phase

Coherence in hybrid texts: The case of the Patient Information Leaflet genre

open access: yesHermes, 2019
This article investigates the degree of coherence in a particular type of hybrid text, viz. the Patient Information Leaflet, which is a lay-oriented genre fusing original and derived textual elements.

Research on the Vortex States of Partially Coherent Vortex Beams

open access: yesPhotonics
The Mutual Optical Intensity (MOI) model is further developed to simulate the propagation of partially coherent X-ray vortex beams through free space. The intensity, phase, and amplitude distributions of the degree of coherence in the far field zone are ...

Propagation Characteristics of a Twisted Cosine-Gaussian Correlated Radially Polarized Beam

open access: yesApplied Sciences, 2018
Recently, partially coherent beams with twist phases have attracted growing interest due to their nontrivial dynamic characteristics. In this work, the propagation characteristics of a twisted cosine-Gaussian correlated radially polarized beam such as ...

Experimental control of the degree of non-classicality via quantum coherence [PDF]

open access: yes, 2020
The origin of non-classicality in physical systems and its connection to distinctly quantum features such as entanglement and coherence is a central question in quantum physics.

Deformed dispersion relations and the degree of the coherence function [PDF]

open access: yesGeneral Relativity and Gravitation, 2006
The analysis of the modifications that the presence of a deformed dispersion relation entails in the roots of the so--called degree of coherence function, for a beam embodying two different frequencies and moving in a Michelson interferometer, is carried out.
