A new instrument has been developed and deployed for sensitive reception of broadband
extremely low frequency (ELF)(defined in this paper as 300-3000 Hz) and very low …

The impact of randomly distributed field‐aligned density irregularities on whistler‐mode
wave propagation is investigated using full‐wave simulations and multipoint spacecraft …

Abstract A Very Low Frequency (VLF) wave detection system has been designed at Wuhan
University (WHU) and recently deployed by the Polar Research Institute of China at the …

Abstract Very low frequency (VLF, 3–30 kHz) transmitter remote sensing has long been used
as a simple yet useful diagnostic for the D region ionosphere (60–90 km). All it requires is a …

For the applications of Alpha very-low-frequency (VLF) systems consisting of multiple
transmitters, determining the origin transmitter station of received signals is a crucial …

The HF dipole array of the High Frequency Active Auroral Research Program (HAARP) in
Gakona, Alaska, was recently upgraded to 180 elements, facilitating operations at a total …

Chorus emissions are generated by a nonlinear mechanism involving wave‐particle
interactions with energetic electrons. Discrete chorus wave packets are narrowband tones …

The analysis of ELF/VLF radio data has broad applications for ionospheric and
magnetospheric phenomena, lightning activity, long-range communications, and …

A new method is proposed for deriving extremely low frequency (ELF) wave arrival azimuths
using the wide range of signal amplitudes, contrary to previously applied high amplitude …

We present a detailed analysis of a long‐lasting quasiperiodic (QP) event observed
simultaneously by the low‐altitude DEMETER spacecraft and on the ground by the …
