The damping of a monochromatic wave propagating at an angle to the magnetic field in an inhomogeneous plasma is studied. The nonlinear equations for resonance particles are solved in the drift approximation. The nonlinear damping decrement is calculated.

Dynamic measurement techniques such as ac resistivity and the Cahill 3-/spl omega/ [1990] thermal conductivity method induce periodic currents in materials. In thermoelectric materials the coupling between electrical and thermal effects means the normal mode excitations are generally attenuated waves of mixed electrical/thermal character.

Radial coherence, wave velocity and damping of electrocortical waves
Electroencephalography and Clinical Neurophysiology, 1991Mean squared coherence was calculated as a function of frequency (1-32 Hz) and electrode separation (1-8 mm) from 64-channel extradural arrays on occipito-parietal association cortex of cats. A 2-parameter theoretical function was then fitted to sets of pooled estimates.

Damping of Periodic Waves in Physically Significant Wave Systems
Studies in Applied Mathematics, 2008Damping of periodic waves in the classically important nonlinear wave systems—nonlinear Schrödinger, Korteweg–deVries (KdV), and modified KdV—is considered here. For small damping, asymptotic analysis is used to find an explicit equation that governs the temporal evolution of the solution.

Damping of magnetohydrodynamic waves in a rotating fluid
Journal of Fluid Mechanics, 2017The long-time evolution of a flow structure subject to background rotation and a coaxial uniform magnetic field is investigated in this paper. The conditions of magnetic Reynolds number$Rm\ll 1$and Rossby number$Ro\ll 1$apply, while the condition of magnetic interaction parameter$N\gg 1$ensures that nonlinear inertial forces are small in the system ...

The viscous damping of atmospheric gravity waves
Canadian Journal of Physics, 1963Dissipation produced by viscous damping and thermal conduction is important in the study of atmospheric gravity waves, which are themselves important in a study of "irregular" motions in the upper atmosphere. The mathematics of this damping is considered in some detail here, and charts are given to assess the effects of viscous damping and thermal ...

Physics of Plasmas, 2005
The damping of plasma waves is considered for both large and small amplitudes. Both reversible and irreversible energy exchanges between the particles and the field during the initial transient are discussed, and a physical picture of these processes is given.

Journal of the Waterways and Harbors Division, 1968
To obtain quietness within a harbor enclosure it is necessary to prevent energy from entering or, to dampen it after it enters. Small craft are responsive to short period waves, which may be effectively reduced within the enclosure. An investigation is underway to determine the response of small craft to various oscillations within a basin ...

Elastic Waves Propagation in Damped Media
2003A Green function technique is employed to investigate the propagation of elastic waves in a semi-infinite damped media. The calculations are based on the linear response function approach, which is very convenient to deal with this kind of problem. Both the displacement and the gradient displacement Green functions are determined.
