The reflection and transmission coefficients through multilayered structure of finite thickness and the dispersive relations of Bloch waves in one-dimension infinite periodic structure (phononic crystals) consisting of two repetitive different micropolar slabs are studied. Due to the additional microrotational degree of freedom, the modes of elastic waves in a micropolar solid are different from that...
The reflection of elastic waves at the boundary of micropolar half-space with the viscoelastic support is studied in this paper. The spring-dashpot model is used to model the viscoelastic support. The boundary condition includes the force stress, couple stress, the displacements and the micro-rotation and the contribution from the spring and the dashpot on them. The amplitude ratios and phase shifts...
