Anomalies Observed in VLF and LF Radio Signals on the Occasion of the Western Turkey Earthquake (Mw = 5.7) on May 19, 2011 [PDF]

open access: yes, 2012
VLF radio signals lie in the 10 - 60 kHz frequency band. These radio signals are used for worldwide navigation support, time signals and for military purposes.

The Radiation Transfer at a Layer of Magnetized Plasma With Random Irregularities [PDF]

open access: yes, 1998
The problem of radio wave reflection from an optically thick plane monotonous layer of magnetized plasma is considered at present work. The plasma electron density irregularities are described by spatial spectrum of an arbitrary form.

Remote sensing planetary waves in the midlatitude mesosphere using low frequency transmitter signals [PDF]

open access: yes, 2011
Very low and low radio frequency (VLF/LF) propagation responds sensitively to the electron density distribution in the lower ionosphere (upper mesosphere).

Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011 [PDF]

open access: yes, 2012
In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these bands, with the measurement for each of them of the ...

Observation of wave-packet propagation in the ion cyclotron range of frequencies in a tokamak plasma [PDF]

open access: yes, 1991
Experimental observation of wave-packet propagation in the ion cyclotron range of frequencies in a tokamak plasma is reported. Studies were carried out in the Caltech Research Tokamak [Phys.

An Improved Split-Step Wavelet Transform Method for Anomalous Radio Wave Propagation Modelling [PDF]

open access: yes, 2014
Anomalous tropospheric propagation caused by ducting phenomenon is a major problem in wireless communication. Thus, it is important to study the behavior of radio wave propagation in tropospheric ducts.

Radio fiber bursts and fast magnetoacoustic wave trains

open access: yes, 2012
We present a model for dm-fiber bursts that is based on assuming fast sausage magnetoacoustic wave trains that propagate along a dense vertical filament or current sheet.

Radio-Wave Propagation and Electromagnetic Surface Waves [PDF]

open access: yesProceedings of the National Academy of Sciences, 1947
A Discrepancy and Its Resolution. - The problem of the propagation of radio-waves along the surface of the (plane) earth was first treated in a celebrated paper by A. Sommerfeld (1909).(1) Let the (r, φ)-plane of a cylindric system of coordinates coincide with the plane of the earth surface and let the z-axis point vertically upward.

Effects of the ISM on Detection of Low-frequency Gravitational Waves

open access: yes, 2013
Time variable delays due to radio wave propagation in the ionized interstellar medium are a substantial source of error in pulsar timing array efforts.
