Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
Anisotropic complex Padeacute hybrid finite-difference depth migration

Electrostatic instabilities induced by large-amplitude left-hand polarized waves
(Blackwell Publishing Ltd, 2004)
We study the effect of a large-amplitude left-hand polarized wave on ion acoustic instabilities. We show that the presence of a finite amplitude left-hand polarized wave produces electrostatic instabilities above a threshold ...
On the elastic wave equation in weakly anisotropic VTI media

Seeding and layering of equatorial spread F by gravity waves
(American Geophysical Union, 1990-10)
Studies dating back more than 15 years have presented evidence that atmospheric gravity waves play a role in initiating nighttime equatorial F region instabilities. This paper analyzes a spectacular spread F event that for ...
Nonlinear Gravitational Waves: Their Form and Effects
(Springer/plenum Publishers, 2013)
Linear kinetic waves in plasmas described by Kappa Distributions
(Elsevier, 2017)
In this chapter we present an overview of the excitation, propagation, and
absorption of linear plasma waves in collisionless, spatially uniform, multicomponent,
magnetized non-Maxwellian plasma characterized by a ...
On the development of nonlinear waves in the equatorial electrojet
(Elsevier, 2013-10)
Theories for the equatorial electrojet (EEJ) have been notoriously difficult to resolve with data. Two of these problems were solved recently and another is discussed in this publication. We initially review solutions to ...
