  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、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。

  4. Abstract : analyzes the performance of unipolar ocdma system using optical orthogonal code ( ooc ) considering the dispersion and nonlinearity effect of the transmission medium. theoretical analysis demonstrates that dispersion and nonlinearity effect deteriorate the system performance. the performance of ocdma system assuming dispersion - shifted fiber as transmission medium is very close to the case neglecting the dispersion and nonlinearity effect. assuming rz initial pulse and optical hard limiter are also possible solutions

    文摘:分析了基於光正交碼（ ooc ）的光碼分多址系統的性能.數值結果表明：與以前忽略光纖通道對系統性能的情況相比，在考慮了光纖的色散和非線性效應以後，系統性能有了明顯的下降.給出了一些建議方案來遏制由色散和非線性效應引起的系統性能惡化
