Incoherent scatter modeling of Jicamarca radar spectra
… on the modeling of spectral characteristics of electron density irregularities of the topside equatorial ionosphere probed by the Jicamarca Incoherent Scatter Radar (ISR) located near Lima, Peru. The topside equatorial ionosphere is a multi-ion plasma and the spectrum of its electron density …

Spectral characteristics of low-frequency variability in compact extragalactic radio sources
… with fluctuations of the refractive index due to electron density irregularities, emerge from that medium corrugated. Since fluctuations present on scales greater than the Fresnel scale act refractively, the emerging wavefront has a curvature which produces a refractive amplification or …

Ionospheric Scintillation Prediction, Modeling, and Observation Techniques for the August 2017 Solar Eclipse
… short term changes to the atmosphere, such as density and temperature alterations. There are many ways to measure these changes, one of these being ionospheric scintillation. Ionospheric scintillation is rapid amplitude and phase fluctuations of signals passing through the ionosphere caused by …

Radio Propagation Through Density Irregularities in the Auroral Ionosphere
… is to investigate the impact of ionospheric density irregularities on radio wave propagation by studying their characteristic features and ionosphere conditions during radio scintillation. We employ a modeling approach using a radio wave 3D propagation model: Satellite-beacon …

The Mid-Latitude Ionosphere: Modeling and Analysis of Plasma Wave Irregularities and the Potential Impact on GPS Signals
… studies reveal that the mid-latitude ionospheric irregularities are less understood due to lack of models and observations that can explain the characteristics of the observed wave structures. Since temperature and density gradients are a persistent feature in the mid-latitude ionosphere near the …
