The current project is concerned with the propagation of waves through thermo elastic media. The medium selected is isotropic in nature; we have also considered the molecular temperature of the particles in terms of micro-temperature. The medium selected is rotating around about an axis with some angular velocity we have also encountered the influence of magnetic effect on plane waves propagating through the elastic medium. Thermal wave generated because of deformation is analyzed by using the three phase lag heat conduction model. The governing system of equations is made dimensionless by special parameters and then equations are decomposed by using Helmhot?s potential functions. Method of Normal mode analysis is used to obtain the exact solution of the field variables. Finally the theoretical results obtained are represented graphically for particular medium.
