Haskell Matrix Method for the Propagation of Love Waves in Multilayers of Magneto-Thermoelastic Materials

The problem of the propagation of Love waves in multilayers of generalized magneto-thermoelastic materials has been investigated using Haskell matrix method. The dispersion relations for the Love waves are derived for the topmost layer with the help of appropriate conditions. We have observed that there are two wavefronts of Love-type surface waves: the first wavefront is due to the electro-magnetic parameters and the second wavefront appears due to the thermal parameters. The dispersion curves of both these fronts are computed for two and three layers and results are represented graphically. The phase velocity corresponding to first wavefront is non-attenuating, while that of second wavefront is attenuating. The 3D pictures of displacement, conductive temperature and heat flux have shown that transverse displacement, conductive temperature and heat flux are sinusoidal natures.
