Seismic metamaterials for low-frequency mechanical wave

WebThe theory and ultimate development for the seismic metamaterial is based on coordinate transformations achieved when concealing a small cylindrical object with electromagnetic waves. This was followed by an analysis of acoustic cloaking, and whether or not coordinate transformations could be applied to artificially fabricated acoustic materials. WebA snowman-like seismic metamaterial is proposed in this study. The proposed model gives a lower and wider complete bandgap compared with the seismic metamaterials of the same volume in previous research. The vibration modes are investigated to clarify the mechanism of bandgap formation. Past studies used large amounts of steel to attenuate …
