| Summary: | This paper presents a study on plane waves propagating in a micropolar piezoelectric material with transverse isotropy. The plane wave solutions of the governing field equations suggest that there exists three coupled plane waves propagating in a micropolar piezoelectric medium. Reflection of a plane wave incident at a non-free surface of a micropolar piezoelectric half-space is considered. The analytical expressions of the reflection coefficients and energy ratios are obtained. A quantitative example is set up to compute the speeds, reflection coefficients and energy ratios of reflected waves. The speeds, energy ratios and reflection coefficients are illustrated graphically against the propagation angle. The numerical results show that the boundary parameters connected to the mechanical nature of the non-free surface affect significantly the energy ratios and reflection coefficients.
