Filter Response

Using a periodic corrugation at the surface of a semi-infinite elastic medium, the incident and reflected Rayleigh modes are strongly coupled when the Bragg condition is satisfied. The method of multiple scales is used to derive the coupled-mode equations describing such an interaction. The filter response is presented in terms of the reflection coefficient. An improved filter response may be obtained by imposing an amplitude taper on the corrugation, resulting in a close to ideal narrower midband response. By further introducing a chirped corrugation, an optimized wider midband response is realized.

Velocity Of Propagation

AbstractIt has been shown that uncoupled surface waves of SH type can be propagated without any dispersion in an electrically conducting semi-infinite elastic medium provided a uniform magnetic field acts non-aligned to the direction of wave propagation. In general, the velocity of propagation will be slightly greater than that of plane shear waves in the medium.
