The present paper analyzes the propagation of Rayleigh waves in a non-local micropolar thermoelastic half space with impedance boundary conditions. Dispersion equation of Rayleigh wave propagation with impedance boundary conditions is obtained and the effect of impedance and non local parameters are studied. Dispersion equation of Rayleigh waves for a micropolar thermoelastic half space with impedance boundary as well as traction free half-space is obtained as a particular case. The non-dimensional speed of Rayleigh wave is computed as a function of impedance parameters and presented graphically for a aluminum epoxy material. It is observed that non local and impedance parameters has significant effects on Rayleigh wave speed.
