Anomalous Love wave phase velocities

Journal of Geophysical Research, 1971
Anomalously high Love wave phase velocities in the period range 60–110 sec have been measured between the station pair La Paz, Bolivia (LPB), and Arequipa, Peru (ARE), of the World Wide Standard Station Network for an earthquake in the Republic of the Congo.

Love waves in double porosity media

Journal of Sound and Vibration, 2006
Abstract Based on the control equations for double-porosity media extended from Biot's theory, the propagation of Love waves is discussed in this paper. Dispersion equations of Love waves in double porosity medium are obtained by utilizing the usual assumption of Love waves in elastic solid with the coupling mass coefficient ρ 23 and coupling ...

The Theory of Love Waves

1967
In this section the displacements in Love waves generated by a nonstationary asymmetric source in a three-dimensional medium are expressed in terms of the solution of the one-dimensional problem considered in Section 2 (i.e., in terms of the characteristic functions of a Sturm-Liouville operator).

Love waves in nonclassical micropolar piezoelectricity

The Journal of the Acoustical Society of America, 1999
The basic equations of the linear theory of the micropolar piezoelectricity with polarization gradient have been derived in the paper ‘‘Polarization gradient in micropolar piezoelectricity,’’ presented at IMSE’98, 10–13 August 1998, Michigan Tech, Houghton, MI. In the case of the two-dimensional problem, the fundamental system of differential equations

Love waves in nonuniform wave guides: Finite difference calculations

Journal of Geophysical Research, 1970
A simple finite difference approximation to the elastic equations of motion is successfully used to solve various wave-propagation problems possessing analytical solutions. On this basis the method is extended to the problem of Love waves propagating across an ocean-continent type boundary. Numerical propagation of an initial transient solution results

Self-induced transparency for love waves

Physics Letters A, 1987
Abstract A theory of self-induced transparency is constructed for the Love wave in a system which consists of a film lying on a semispace in the presence of paramagnetic impurities. The solution is obtained in the form of the 2π-pulse of McCall and Hahn for the Love wave.

Seismic metasurfaces for Love waves control

2018
Elastic metasurfaces consist of resonant inclusions or resonant oscillators, placed at the free surface of an elastic medium, which collectively interact with surface elastic waves to redirect, steer or absorb their energy. Metasurfaces of vertical oscillators over homogeneous elastic half-spaces can inhibit the propagation of vertical polarized waves (

Love waves in an inhomogeneous interstratum

pure and applied geophysics, 1970
The propagation of Love waves in an inhomogeneous interstratum, whose rigidity and density follow generalized power law variation, lying between two homogeneous half-spaces has been considered. The characteristic frequency equations have been obtained.
