The present problem has been formulated to understand the working of surface acoustic wave devices under the viscous liquid loading. An analytical study has been employed to compute the group velocity of Love-type waves in composite structure consists of functionally graded material layer embedded over magnetoelastic self-reinforced substrate immersed in viscous fluid. Profound effects of the material gradient, magneto-elasticity, initial stress, viscosity and liquid mass density on the group velocities are observed and depicted by means of graphs. It is revealed from the study that the group velocity of Love-type waves diminishes with increasing values of both density and viscosity of the viscous liquid.

目前的问题已经制定以了解表面声波器件在粘性液体负载下的工作。已采用分析研究来计算复合结构中 Love 型波的群速度，该复合结构由嵌入在粘性流体中的磁致弹性自增强基板上的功能梯度材料层组成。观察到材料梯度、磁弹性、初始应力、粘度和液体质量密度对群速度的深刻影响，并通过图表描述。研究表明，Love型波的群速度随着粘性液体的密度和粘度值的增加而减小。
