In this work, the propagation behaviour of a surface wave in a micropolar elastic half-space with surface strain and kinetic energies localized at the surface and the propagation behaviour of an interfacial anti-plane wave between two micropolar elastic half-spaces with interfacial strain and kinetic energies localized at the interface have been studied. The Gurtin–Murdoch model has been adopted for surface and interfacial elasticity. Dispersion equations for both models have been obtained in algebraic form for two types of anti-plane wave, i.e. a Love-type wave and a new type of surface wave (due to micropolarity). The angular frequency and phase velocity of anti-plane waves have been analysed through a numerical study within cut-off frequencies. The obtained results may find suitable applications in thin film technology, non-destructive analysis or biomechanics, where the models discussed here may serve as theoretical frameworks for similar types of phenomena.

“…The continuous change into the off-axis modulus leads to wave mode conversion [74]. The propagation of waves having high frequencies or short wave lengths [75], in particular, when the wave length is of the same order of magnitude as the average dimension of the microelements, the intrinsic motion of the micro-elements with respect to the center of mass affects the outcome appreciably [76].…”

“…Love type wave propagation in an uneven piezoelectric structure, Singh et al [26]. Regarding the effect of irregularities on the SH-type direction of propagation inside the micropolar elasticity composite structure, Singh et al [27] came across some comments. Love-type waves in the couplestress stratum that were ill-bonded to an uneven viscous substrate were discussed by Ray and Singh [28].…”

The current study examines the behavior of an SH wave traveling over a functionally graded magneto-elastic substrate arrangement. At the substrate-vacuum interface, two irregularities with different shapes-rectangular and parabolically shaped-are considered in electrically and magnetically open cases and electrically and magnetically short cases. A study is also done on the combined impact of inhomogeneity, depth source, and irregularity. With the help of the Fourier transform, inverse Fourier transform, and perturbation technique, complex frequency relation has been derived for each type of irregular interface. The results' key characteristics are highlighted. In order to know the impact of the parameters involved, a particular model consisting of BaTiO3-CoFe2O4 magneto-electro-elastic material has been taken. The findings were presented in the form of graphs, which were created using Mathematica 7. Graphs are plotted for variations in wavenumber and phase velocity. This calculation model could be the ideal match for laminated FGMEE structures utilized as surface acoustic wave devices since the variation of the film's magneto-electromechanical characteristics changes gradually with depth and throughout the production process (SAW). As a result, it can serve as a theoretical foundation for the design of high-performance SAW devices.
