18、d thermoelastic waves have been considered in isotropic media by Puri(1973;1975),Agarwal(1979),and Tao and Prevost(1984).The interaction of generalized thermoelastic waves with anisotropic media was studied by Banerjee and Pao(1974),and Sharma et al.(1986;1989)Guided waves were considered by several

19、 researchers.Nayfeh and Nemat(1971),Sinha(1975)studied thermoelastic Rayleigh waves.Harinath et al.(1976)studied Stonely-type waves.Mondal et al.(1973),Massalas(1986)considered the propagation of generalized thermoelastic waves in thin plates.Erby and Sunhubi(1986)studied the problem of longitudinal
