近年來不少學者投入超材料設計與應用之相關研究，其概念透過共振及等效關係可以達到抗震的效果，然而，超材料在真實應用上，材料空間及計算過於龐大且複雜，隨著科技的進步，近幾年興起來一項新穎的超材料研究－超穎介面(metasurfaces)，透過特殊單元結構設計及週期性排列方式，不同於超材料，超穎介面僅利用微小尺度的介面結構即可使波傳有轉向的現象，本論文主要為探討超穎介面在聲波及彈性波領域設計上的差異，首先介紹廣義司乃耳定律以了解波傳在超穎介面內部傳遞時的依據，再來介紹聲波超穎介面及彈性波超穎介面的設計，前者是利用多種材料；後者則利用單一材料但不同比例設計，並藉由更改介面及材料參數來探討其對波傳結果的影響，並在後續利用聲波超穎介面設計的方式來設計新型彈性超穎介面，藉由數值模擬與數學推導，觀察並統整超穎介面各參數的改動對波傳結果的影響。

With the advancement of science and technology, a novel metamaterial has emerged in recent years known as metasurfaces. It uses designed unit structure and periodic arrangement. Unlike metamaterials, metasurfaces only use tiny scales. The interface structure can make the wave propagation tunable. In this paper, in order to design elastic metasurfaces with wave transmission mechanism, introducing the generalized Snell’s law to understand the internal guiding mechanism of the metasurfaces, then introducing the acoustic metasurfaces. In the design, compared the wave propagation results by adjusting the parameters in the interface, then introduced the design of the elastic wave metasurfaces, and comparing the possibility of the design and the change of parameters of the acoustic and the elastic metasurfaces. Finally, using the acoustic metasurfaces design to simulate the elastic metasurfaces, then discuss the difficulties of the new metasurfaces design.
