Time-domain ptychography [PDF]

open access: yesPhysical Review A, 2015
Through dedicated measurements in the optical regime we demonstrate that ptychography can be applied to reconstruct complex-valued object functions that vary with time from a sequence of spectral measurements. A probe pulse of approximately 1 ps duration, time delayed in increments of 0.25 ps is shown to recover dynamics on a ten times faster time ...

A time domain anti-jamming processing algorithm for GNSS ranging receiver

open access: yesFrontiers in Physics, 2022
Traditional anti-jamming algorithms lead to a deviation of the Global Navigation Satellite System receiver’s ranging value, which has become the main obstacle to the improvement of the accuracy of the high-precision ranging receiver.

Finite Element Modelling and Simulation of the Hysteretic ‎Behaviour of Single- and Bi-metal Cantilever Beams using a ‎Modified Non-linear Beta-damping Model [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
This paper explores a novel non-linear hysteresis model obtained from the modification of the conventional Kelvin-Voigt model, to produce a non-viscous hysteretic behaviour that is closer to metal damping. Two case studies are carried out for a vibrating

Analysis of Nonlinear Time-Domain Lubrication Characteristics of the Hydrodynamic Journal Bearing System

open access: yesLubricants, 2023
The nonlinear time-domain lubrication characteristics of the hydrodynamic journal bearing system are studied in this paper. The motion equation of the hydrodynamic journal bearing system is established based on the balance of the relationship among the ...

Optical Supersymmetry in the Time Domain [PDF]

open access: yes, 2019
Originally emerged within the context of string and quantum field theory, and later fruitfully extrapolated to photonics, the algebraic transformations of quantum-mechanical supersymmetry were conceived in the space realm.

Superlens in the Time Domain [PDF]

open access: yesPhysical Review Letters, 2012
It has been predicted theoretically and demonstrated experimentally that a planar slab supporting surface plasmons or surface phonon polaritons can behave as a super lens. However, the resolution is limited by the losses of the slab. In this letter, we point out that the resolution limit imposed by losses can be overcome by using time-dependent ...

Gravitational Waves and Time Domain Astronomy [PDF]

open access: yes, 2011
The gravitational wave window onto the universe will open in roughly five years, when Advanced LIGO and Virgo achieve the first detections of high frequency gravitational waves, most likely coming from compact binary mergers. Electromagnetic follow-up of

Time domain Einstein-Podolsky-Rosen correlation [PDF]

open access: yes, 2006
We experimentally demonstrate creation and characterization of Einstein-Podolsky-Rosen (EPR) correlation between optical beams in the time domain. The correlated beams are created with two independent continuous-wave optical parametric oscillators and a ...

Flow-Heat Conjugate Numerical Simulation Based on the Time-Domain Method

open access: yesXibei Gongye Daxue Xuebao, 2020
For the popups of the applicability of the time-domain based unsteady flow-heat coupling numerical simulation method in physical problems with time-period characteristic, the cases of the plate convection heat transfer and the hollow blunt-nosed blade ...
