摘要： This article delves into the intricate dynamics of Rayleigh wave propagation within a nonlocal orthotropic medium, where the presence of void and diffusion adds an intriguing layer to the analysis. Grounded in Eringen nonlocal elasticity theory and embracing the three-phase-lag model of hyperbolic thermoelasticity, the study focuses on the interplay between the mass diffusion principles of Fick and the Fourier law under the framework of hyperbolic thermoelasticity. The investigation employs a methodological approach centered around normal mode analysis to navigate the complexities of the problem at hand. The derived frequency equation governing Rayleigh waves undergoes meticulous scrutiny through the exploration of specific cases. The elliptical trajectory of surface particles and its eccentricity during Rayleigh wave propagation are identified and calculated.
