Effect of Density Irregularities on Radio Frequency Wave Propagation in Ionospheric Plasmas [PDF]
EPJ Web of ConferencesDensity irregularities play a vital role in determining how radio frequency (RF) waves travel through plasmas. In the Earth’s ionosphere, these density irregularities also impact radio communication.

Probing electromagnetic wave energy with an in-series assembly of thermoelectric devices
AIP Advances, 2022 We study the interaction of radio waves, microwaves, and infrared laser light of power P and period τ with a macroscopic thermoelectric (TEC) device-based detector and probe the energy Pτ as being the energy of these electromagnetic (EM) waves.

Double plasma resonance instability as a source of solar zebra emission
, 2017 The double plasma resonance (DPR) instability plays a basic role in the generation of solar radio zebras. In the plasma, consisting of the loss-cone type distribution of hot electrons and much denser and colder background plasma, this instability ...

Transport properties of Andreev polarons in superconductor-semiconductor-superconductor junction with superlattice structure [PDF]
, 2011 Transport properties of a superconductor-semiconductor-superconductor (S-Sm-S) junction with superlattice structure are investigated. Differential resistance as a function of voltage shows oscillatory behavior under the irradiation of radio-frequency (RF)

On the Escape of Low-frequency Waves from Magnetospheres of Neutron Stars
The Astrophysical Journal, 2023 We study the nonlinear decay of the fast magnetosonic (fms) into the Alfvén waves in relativistic force-free magnetohydrodynamics. The work has been motivated by models of pulsar radio emission and fast radio bursts (FRBs), in which the emission is ...

Nonthermal Emissions from Particles Accelerated by Turbulence in Clusters of Galaxies [PDF]
, 2002 We consider nonthermal emission from clusters of galaxies produced by particle acceleration by resonant scattering of Alfv\'{e}n waves driven by fluid turbulence through the Lighthill mechanism in the intracluster medium. We assume that the turbulence is

Radio Astronomical Polarimetry and the Lorentz Group [PDF]
, 1999 In radio astronomy the polarimetric properties of radiation are often modified during propagation and reception. Effects such as Faraday rotation, receiver cross-talk, and differential amplification act to change the state of polarized radiation.
