Abstract
Propagation problem for coupled harmonic waves of translational displacements and microrotations along the axis of a long cylindrical waveguide is discussed at present study. Microrotations modeling is carried out within the linear micropolar elasticity frameworks. The coupled system of vector differential equations of micropolar elasticity is presented. The translational displacements and microrotations in the coupled wave are decomposed into potential and vortex parts. The coupled differential equations are then reduced to uncoupled ones. The wave equations solutions for the translational and microrotational waves potentials are obtained for a high-frequency waves in the cylindrical domain.
