Table 2.
Comparative table of band gap characteristics before and after optimization for radial seismic metamaterials with four commonly used engineering core shapes.
| Core shape | Pre-optimization | Post-optimization | Bandgap width increase |
|---|---|---|---|
| bandgap range (Hz) | bandgap range (Hz) | after optimization (Hz) | |
| L-shaped | 9.5–23.30 | 10.061–26.568 | 2.707 |
| T-shaped | 9.77–26.19 | 10.923–34.681 | 7.338 |
| I-shaped | 8.93–24.64 | 11.534–30.948 | 3.704 |
| Channel-shaped | 9.40–28.62 | 11.274–31.225 | 0.731 |
