本文研究了横波在两种不同类型纤维增强材料界面上沿平面传播的可能性。上层为纤维增强层，下半层为非均匀纤维增强层。给出了紧凑形式的频散方程和地表附近能量流最大的条件。对于均匀介质，频散方程与Love波的频散方程一致。用图形描述了强化和非均匀对相速度和群速度的影响。结果表明，不均匀和配筋降低了相速度，配筋的存在偏离了群速度。
This paper investigates the possibility of shear wave propagation along the plane surface in the interface of two different types of fibre reinforced media. The upper layer is fibre reinforced and the lower half-space is taken inhomogeneous fibre reinforced. Dispersion equation and condition for maximum energy flow near the surface are obtained in compact form. The dispersion equation coincides with that of Love wave for uniform media. Effect of reinforcement and inhomogeneity on phase and group velocity has been depicted by means of graphs. It is observed that inhomogeneity and reinforcement decreases the phase velocity and presence of reinforcement deviate the group velocity.
