Abstract
- This study considers the propagation of harmonic plane waves in general anisotropic dissipative media. This propagation is governed by a complex slowness vector, which is resolved into a propagation vector and an attenuation vector. The attenuation part is decomposed into homogeneous attenuation and evanescent attenuation. This makes a generalised specification of slowness vector to represent (in)homogeneous propagation in (an)isotropic (an)elastic media. This specification applies to incident waves, scattered waves as well as surface/interface waves at the plane boundary of the medium. With the choice of involved parameters, this specification can represent the corresponding wave-fields in the absence of anisotropy and/or dissipation. This specification has been used to formulate a corrected procedure for the reflection of plane waves in a transversely isotropic piezothermoelastic medium. [ABSTRACT FROM AUTHOR]
