Abstract. Love wave propagation in layered media parallel to the layers of the structure along the cylindrical surfaces with homogeneous boundary conditions is investigated. As part of the study, a dispersion equation was obtained and solved with respect to the wave number. Based on the obtained solutions, graphical dependences of the wave propagation velocity on the ultrasound frequency are plotted, and the influence of the surface curvature radius on the wave velocity is shown.

Keywords: Love wave, dispersion equation, layered medium, cylindrical surface, homogeneous boundary conditions
