ABSTRACT Seismic wave isolation through layered meta‐foundations is an emerging area of research, driven by its intrinsic theoretical significance and potential practical applications. To date, the complexities associated with imperfect interfaces have often been overlooked in development analytical frameworks, which tend to prioritize simple yet effective closed‐form dispersion laws. This work provides a further step toward study under real‐world conditions incorporating effects interfaces. Our developed framework demonstrates that accounting for interface markedly enhances ultra‐low‐frequency attenuation meta‐foundations, as revealed complex analysis verified transmission finite‐sized meta‐foundations. enhancement achieved modifying stiffness mass interfaces, affects both location width frequency zones (AZs) improves within these domains. Overall, our incorporate demonstrate superior performance compared traditional offers model explores imperfections on their dynamic properties, paving way advancements design novel artificial
