Low frequency electromagnetic radiation coming from gravitational waves generated by neutron stars [PDF]
, 2017 We investigate the possibility of observing very low frequency (VLF) electromagnetic radiation produced from the vacuum by gravitational waves. We review the calculations leading to the possibility of vacuum conversion of gravitational waves into ...

A Novel Strategy for Improving the Aeromagnetic Compensation Performance of Helicopters
Sensors, 2018 An aeromagnetic survey is an important method in magnetic anomaly detection and geophysical prospecting. The magnetic field is typically measured by optically pumped magnetometers (OPM) installed on the aircraft.

A method for separating O-wave and X-wave and its application in digital ionosonde
Annals of Geophysics, 2014 Separation for O wave and X wave is a very important job in interpretation of ionograms, which is premise for automatic scaling. In this paper, a new digital method for separating O wave and X wave is presented, based on a numerical synthesizing ...

Multi-quasi-parabolic ionosphere model with EF-valley
Annals of Geophysics, 2016 We improve the conventional multi-quasi-parabolic (MQP) model and develop two MQP models with EF-valley by applying the predicted EF-valley parameter of the newest version of the International Reference Ionosphere.

Plasma-wave generation in a dynamic spacetime [PDF]
, 2016 We propose a new electromagnetic-emission mechanism in magnetized, force-free plasma, which is driven by the evolution of the underlying dynamic spacetime.
