Models　of　generalized　magneto-thermo-elasticity　based　on　the　Lord-Shulman　theory　(LS)　with　one　relaxation　time,　the　Green-Lindsay　theory　(GL)　with　two　relaxation　times,　as　well　as　the　classical　dynamic　coupled　theory　(CD),　are　used　to　study　the　electro-magneto-thermo-elastic　interactions　in　a　semi-infinite　perfectly　conducting　solid.　The　elastic　medium　rotates　with　uniform　angular　velocity.　The　initial　magnetic　field　is　parallel　to　the　boundary　of　the　half-space.　Reflection　of　magneto-thermo-elastic　waves　under　generalized　thermo-elasticity　theory　is　studied.　The　reflection　coefficients　are　obtained.　(C)　2007　Elsevier　Ltd.　All　rights　reserved.
