4.3. The Attenuation Effect of OS-RGSM Structure on Surface WaveIn order to further study and optimize the attenuation effect of OS-RGSM on seismic surface waves, finite element simulation calculations were performed using COMSOL Muiltiphysics 5.5. In theory, the infinite periodic unit cell structure has ideal filtering characteristics. However, in practical engineering applications, the number of unit cells is always limited.
