Lamb mode diversity imaging for non-destructive testing of plate-like structures
(2013-07-18)
Several Lamb wave modes can be coupled to a particular structure, depending on its geometry and transducer used to generate the guided waves. Each Lamb mode interacts in a particular form with different types of defects, ...

Ultrasound imaging of immersed plates using high-order Lamb modes at their low attenuation frequency bands
(2017-11-01)
This paper focuses on the use of a Lamb wave-based methodology for ultrasound imaging of immersed plate structures. In these cases Lamb waves can be strongly attenuated due to leaky waves and viscous losses in the liquid, ...
Waves and turbulence in magnetohydrodynamic direct numerical simulations
(American Institute of Physics, 2009-12)
Direct numerical simulations of the incompressible MHD equations with a uniform background magnetic field in a turbulent regime are performed to assess the relative importance of broadband turbulent fluctuations and wavelike ...

Several Lamb wave modes can be coupled to a particular structure, depending on its geometry and transducer used to generate the guided waves. Each Lamb mode interacts in a particular form with different types of defects, ...
Resonant Wave Interactions in the Equatorial Waveguide
(AMER METEOROLOGICAL SOC, 2008)
Weakly nonlinear interactions among equatorial waves have been explored in this paper using the adiabatic version of the equatorial beta-plane primitive equations in isobaric coordinates. Assuming rigid lid vertical boundary ...
Tropical Intraseasonal Modes of the Atmosphere
(Reviews In Advance. vol 39: 5.1–5.27, 2014-08-06)
Tropical intraseasonal variability (TISV) of the atmosphere describes the coherent variability in basic state variables, including pressure, wind, temperature, and humidity, as well as in the physical phenomena associated ...
Stochastic electron acceleration by temperature anisotropy instabilities under solar flare plasma conditions
(IOP Publishing, 2022)
Using 2D particle-in-cell plasma simulations, we study electron acceleration by temperature anisotropy instabilities, assuming conditions typical of above-the-loop-top sources in solar flares. We focus on the long-term ...
Scattering of e Polarized Whispering-Gallery mode from Concave BoundaryScattering of e Polarized Whispering-Gallery mode from Concave Boundary
(2012-03-01)
In this work we present numerical results for the 2D problem of scattering E polarised whispering-gallery mode from concave convex perfectly conducting boundary. The results were obtained by applying the developed method ...
