Dispersion curves for the generalized Bernstein modes [PDF]
Journal of Plasma Physics, 1973 Dispersion curves are plotted for the extraordinary branch of the electron- and ion-cyclotron harmonic waves propagating perpendicularly to the static magnetic field in a non-relativistic, hot Maxwellian plasma, without invoking the electrostatic approximation.

On the effect of damping on dispersion curves in plates
International Journal of Solids and Structures, 2013 AbstractThis paper presents a study on quantitative prediction and understanding of time-harmonic wave characteristics in damped plates. Material dissipation is modelled by using complex-valued velocities of free dilatation and shear waves in an unbounded volume. As a numerical example, solution of the classical Rayleigh–Lamb problem for a viscoelastic

A semi-analytical method for identification of thin elastic plate parameters basing on LWM
Computer Assisted Methods in Engineering and Science, 2017 A new semi-analytical method, discussed in the presented paper, is composed of two stages. Stage A corresponds to the direct analysis, in which the Lamb Waves Measurements (LWM) technique enables obtaining an experimental set of points , where f and k ...
