Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation

open access: yesNew Journal of Physics, 2013
Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

Turbulent parameters at different heights in the atmosphere. Shack–Hartmann wavefront sensor data

open access: yesSolar-Terrestrial Physics, 2022
The paper presents the results of studies of wavefront distortions at different heights in the atmosphere. We have used measurement wavefront data to determine optical turbulence parameters along the line of sight of the Large Solar Vacuum Telescope ...

Impact of voltage subharmonics and interharmonics on currents in single-phase induction motors

open access: yesScientific Journal of Gdynia Maritime University, 2021
In very low power drives, a single-phase induction motor is used. This motor, like the 3-phase induction squirrel-cage motor, requires a voltage supply with suitable parameters – of suitable quality, in practice.

Single-Line-to-Ground Fault Location in Resonant Grounded Systems Based on Fault Distortions

open access: yesIEEE Access, 2021
Under single-line-to-ground (SLG) faults, the voltages and currents in resonant grounded systems will inevitably be distorted. To locate the faults quickly and accurately, this paper proposes a location method based on fault distortions. The faulty phase

Anti-Jamming GNSS Antenna Array Receiver with Reduced Phase Distortions Using a Robust Phase Compensation Technique

open access: yesRemote Sensing, 2023
Antenna arrays with adaptive filtering can protect the integrity and functionality of global navigation satellite system (GNSS) receivers against interference. However, a major problem with existing adaptive array processing algorithms is that they cause

Breathing distortions in the metallic, antiferromagnetic phase of LaNiO$_3$

open access: yesSciPost Physics, 2018
I study the structural and magnetic instabilities in LaNiO$_3$ using density functional theory calculations. From the non-spin-polarized structural relaxations, I find that several structures with different Glazer tilts lie close in energy. The $Pnma$

Analysis of Multi-Antenna GNSS Receiver Performance under Jamming Attacks

open access: yesSensors, 2016
Although antenna array-based Global Navigation Satellite System (GNSS) receivers can be used to mitigate both narrowband and wideband electronic interference sources, measurement distortions induced by array processing methods are not suitable for high ...
