The equations leading t o t h e calculation of the amplitude
ratios of t h e reflected and refracted waves to t h e incident quasilongitudinal
and quasitransversal waves at a boundry surface between two transversely
isotropic media have, been derived along with their polarisation directions.
Some interesting specialisations of the equations have also been given.
The amplitude ratios of the derived waves have been calculated for the
incident quasilongitudinal wave, when the symmetry axes of the media
coincide with t h e normal to t h e boundry surface. The influence of varying
t h e different elastic parameters has been presented in t h e diagrams
