Abstract : This research explores the behavior of shear horizontal (SH) waves as they propagate through a unique size-dependent configuration where a stratum of fluid-saturated nonlocal fissured porous material overlays a substrate comprising nonlocal flexomagnetic material. The analysis focuses on how parabolic interfacial irregularity, nonlocality, and flexomagnetic effect jointly influence SH-wave behavior. By applying the Fourier transform alongside perturbation techniques, complex frequency relation is determined to describe SH-wave propagation across the irregular interface. The dispersion and damping properties of the waves are extracted from the real and imaginary components of the frequency relation. Key parameters, such as the flexomagnetic coefficient, shape of the interfacial irregularity, porosity, piezomagnetic properties, and nonlocality are evaluated for their impact on wave propagation. The results reveal that parabolic interfacial irregularity and flexomagnetic effects significantly modify SH-wave dispersion and damping characteristics. The study underscores the material-dependent nature of wave propagation in such complex layered systems and validates the proposed model through consistency with established wave propagation theories.
