| Summary: | 碩士 === 國立成功大學 === 土木工程學系 === 107 === Inspired by recent demonstrations of wave manipulation with seismic metamaterials, we propose the concept of quantifying the energy dissipation effect. Firstly, we briefly introduce the energy dissipation mechanism of metamaterials and design the unit cell based on the effective medium theory. Secondly, the energy dissipation effect is analytically derived based on Snell's law. Considering the real-scale energy dissipation reaction, the model in frequency domain and in time domain are established by the finite element program. Lastly, we propose a method of evaluating the energy dissipation effect in a large-scale spatial configuration.
