Propagation of Acoustic Gravity Waves in a Finite Depth Water Over a Magnetoelastic Half-Space

The propagation of acoustic gravity waves in a compressible fluid of finite depth is discussed. The fluid considered here is bounded above by free surface and below by an infinite magnetoelastic layer of constant magnetic field. Frequency relationship satisfied by acoustic wave modes has been calculated. Different physical parameters are obtained analytically. Numerical investigation of the results is given for different progressive wave modes. A comparison of the results of the present problem with the case of rigid bottom is given.
