In 1992, a. enders and g. nimtz researched the propagation of microwave signal through several different cutoff waveguides with hp8510b network analyzer ( na ) system and hp70820 transition analyzer ( ta ) system. since 1990s, emig, martin and landauer have been investigating the propagation of electromagnetic pulse through a waveguide with piecewise different dielectric constants
1992年，德國科隆大學的enders和nimtz採用hp8510b網路分析儀系統和hp70820轉換分析儀系統研究了不同結構的截止波導中的信號傳播。從90年代開始， emig和martin 、 landauer等人研究了分段填充不同介質的波導中的電磁脈沖波的傳播。We build a close vibration compensation system which can successfully achieve the measurement of interference fringes movement and - vibration compensation. it puts forward pre - setting fill - in pulses method to implement phase shifting with the same pzt. with this new method, the interference fringe can be stabilized at any pre - setting phase position
提出了填充脈沖數預設定的方法，可以將干涉條紋鎖定在任意設定的位相位置，實現了用pzt同時實現振動補償和移相測量；深入分析討論了pzt的延遲問題，創造性地提出了用多次逼近補償的辦法，給出了反饋補償的演算法，解決了補償過程中存在的系統不穩定和過補償的問題。By using msp430 micro controller unit and cpld technology, this method realized twofold frequency phase ranging : the rough measurement of the distance is realized by countering high frequency pulses which are filled in discriminating phase pulses ; the accurate discriminating phase pulses are converted by using the method of time to voltage conversion, and then the adc device samples the converted voltage, so the accurate measurement of the distance is obtained by processing the adc samples through micro controller unit
該方法通過msp430單片機和先進的cpld技術實現雙頻測相:粗測通過採用對鑒相脈沖填充高頻脈沖的辦法來實現;精測則利用時間-電壓轉換法對鑒相脈沖進行轉換，然後由模數轉換器adc對轉換電壓進行采樣，通過單片機對adc的輸出值進行計算處理獲得精測值。In this paper, first, the study of the distribution of electromagnetic field, energy, power, reflection coefficient and transmission coefficient in waveguide with piecewise different dielectric constants are studied. then, the behavior of propagation of am signal and gauss pulse signal through the waveguide are simulated by magic code ， and the plots of electromagnetic field, energy, ponyting vector and their spectrums at different time and different position are obtained. and, the group velocity and energy velocity of wave packet through barrier are calculated
從90年代開始， emig和martin 、 landauer等人研究了分段填充不同介質的波導中的電磁脈沖的傳播。在本論文中，作者首先推導出分段填充不同介質的波導中的電磁場分佈、能量、傳輸功率以及反射系數和傳輸系數的表達式，然後，採用magic程序模擬了這種波導結構中電磁波的傳播情況，得到了在不同時刻和不同位置處的電磁場分布圖、能量圖、坡印廷矢量圖以及它們的頻譜圖，並由模擬結果計算了波包穿越勢壘的群速和能量速度。分享友人
