  1. 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、、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置處的電磁場分布圖、圖、坡印廷矢圖以及它們的頻譜圖,並由模擬結果計算了波包穿越勢的群速和速度。
  2. One reason for that is the dismatching of effective mass and dielectric constant between the well and the barrier, another important reason is the consideration of the correlation between confined and non - confined direction in the wider well condition

    其原因是除了考慮了阱中電子有川北帥他人學顧十研究生學論義蘇會效質及介電常數的失配性外,更重要的是在寬階時不忽略限制方向與非限制方向的相關性因素
