近幾年抗震領域興起了一項新穎的減震理論—地震超材料，其透過於震波
頻率下激發單元結構的局部共振，使地震能量衰減於傳播路徑之中，而本論文的目標為量化地震超材料的減震效益，首先從等效介質理論出發探討超材料的消能機制並設計單元結構，接著藉由彈性波司乃耳定律求得理論上超材料等效介質的消能效果，並與有限元素軟體所建立的實尺超材料模型之頻域模擬結果相互比較，然而地震波有著與時間相依的特性，因此本論文亦討論超材料於時間域上的消能情形，並在最後提出評估大域空間下地震超材料減震效益的模擬方向。

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.
