Description
Purpose: This study investigates Love-type wave propagation in a multilayered structure composed of a viscous liquid (VL) layer, a piezomagnetic (PM) layer, and a heterogeneous half-space (HHS). It considers two models: Model 1 (Terfenol-D) and Model 2 (Cobalt Ferrite). Wave behaviour is analysed under magnetically open (MO) and short (MS) circuit conditions. Methods: The dispersion relation for Love-type waves was derived analytically, and phase velocity graphs were displayed and analysed in Mathematica. A thorough analysis was conducted to establish the impact of critical variables on phase velocity, including material heterogeneity, piezomagnetic coupling, and viscous liquid layer thickness. Findings: Both models show significant effects of VL and PM coupling on phase velocity. Terfenol-D (Model 1) displays higher sensitivity to piezomagnetic effects, while Cobalt Ferrite (Model 2) shows steadier trends. MO and MS conditions yield comparable results, indicating minor boundary effects. Research limitations: The model only considers linear wave transmission and excludes nonlinear effects. Furthermore, the technique is predicated on idealised material properties that account for heterogeneity. Practical Implications: The studys findings can be used to design and develop energy harvesters, sensors, and wave manipulation instruments using PM with viscous liquid coatings. Understanding the behaviour of surface waves, including phase velocity, is essential for efficient application in these frameworks.
