This simulation is based on Mason equivalent circuit model and transfer matrix method. Besides, the Smith chart, Return Loss and Transducer Loss have been carried out. The theory is applied to a piezoelectric device which excite 1.064μm acoustic wavelength to propagate in the substrate, three different materials of substrate have been chosen in the discussion. By using the Matlab simulation, several important factors including the influence of the bonding layer that affects the performance of piezoelectric transducers have been studied. Furthermore, the designs of matching network will be discussed. Finally, a piezoelectric device’s design procedure to offer a systematic way for the optimum designs of piezoelectric devices is presented.中文摘要……………………………………………………………..i 英文摘要……………………………………………………………..ii 目錄………………………………………………………………......iii 表目錄………………………………………………………………..v 圖目錄………………………………………………………………..vi 符號表………………………………………………………………..ix 第一章　　緒論……………………………………………………..1 1.1 研究動機……………………………………………………1 1.2 文獻回顧……………………………………………………2 1.3 論文架構……………………………………………………4 第二章　　壓電換能器原理………………………………………..5 2.1 壓電材料之基本方程式……………………………………6 2.2 Mason等效電路 …………………………………………….9 第三章　　壓電元件之分析與匹配……………………………….12 3.1 輸入阻抗.…………………………………………………12 3.2 壓電換能之效率分析…………………………………….16 3.3 加入匹配電路之輸入阻抗……………………………….19 3.4 黏著層作為匹配層……………………………………….21 第四章　　壓電元件之數值分析及設計…………………………..24 4.1 摸擬之參數………………………………………………..24 4.2 理想換能器之共振效應…………………………………..24 4.3 各參數對換能器特性之影響……………………………..26 4.3.1 電極面積……………………………………………26 4.3.2 壓電層厚度…………………………………………28 4.3.3 基體厚度……………………………………………29 4.3.4 黏著層材料…………………………………………30 4.3.5 黏著層厚度…………………………………………32 4.3.6 頂電極層……………………………………………33 4.4 匹配電路…………………………………………………..34 4.5 壓電元件之設計…………………………………………..35 第五章　　結論與未來研究方向…………………………………..37 5.1 結論………………………………………………………..37 5.2 未來研究方向……………………………………………..38 參考文獻……………………………………………………………..391416591 bytesapplication/pdfen-US壓電換能器作動器匹配等效電路傳輸矩陣黏著層PiezoelectricTransducerActuatorMatchingBondingTransducer lossthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/51086/1/ntu-94-R92525007-1.pdf
