The improvement of fiber-detection method to enhance the output of amplify-received relaying on FSO communications [PDF]
International Journal of Electronics and Telecommunications, 2023 The performance of free-space optical (FSO) communications that using an optical amplifier (OA) in the scheme of an amplify-received (AR)-relaying has a major drawback in the detection of input signal quality under the effects of turbulence.

Features of cyanine dyes aggregation on differently charged TiO2 matrices
Chemical Physics Impact, 2023 Changing the polycondensation reaction route, positively and negatively charged TiO2 nanoparticles have been synthesized. On the base of the synthesized TiO2 nanoparticles, porous TiO2 films have been formed with different surface charges.

Towards the possibility to combine LOFAR and GNSS measurements to sense ionospheric irregularities
Journal of Space Weather and Space Climate, 2023 Inhomogeneities within the ionospheric plasma density affect trans-ionospheric radio signals, causing radio wave scintillation in the amplitude and phase of the signals.

Observations and modeling of scintillation in the vicinity of a polar cap patch
Journal of Space Weather and Space Climate, 2022 Small-scale ionospheric plasma structures can cause scintillation in radio signals passing through the ionosphere. The relationship between the scintillated signal and how plasma structuring develops is complex.

The Effect of Midnight Temperature Maximum Winds on Post‐Midnight Equatorial Spread F
Space Weather, 2021 The SAMI3/equatorial spread F (Sami3 is also a model of the ionosphere/ESF) code is used to simulate the growth of equatorial plasma bubbles in the presence of a background wind field based on measured winds.

Scintillation Increase Induced by Focusing (Invited)
Photonics, 2023 We show that the focusing of a random electromagnetic beam by a lens gives rise to a scintillation index at the geometrical focus that generally differs from that of the incident beam.

On the Relationship between Low Latitude Scintillation Onset and Sunset Terminator over Africa
Remote Sensing, 2021 The solar terminator is a moving boundary between day-side and night-side regions on the Earth, which is a substantial source of perturbations in the ionosphere. In the vicinity of the solar terminator, essential parameters like S4 index measurements are
