  2. Localization underground target algorithm base on the best automatic curve fitter can survey velocity of electromagnetic wave in underground medium, and locate underground target. it ’ s virtue is small number of operation times. it ’ s shortcoming is subject to clutter

    基於自動最佳擬合曲線的波速測定和目標定位方法可以比較準確地計算出波速，計算出目標位置，優點是運算量小，缺點是容易受到雜波干擾的影響。
  3. 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. By a large amount of calculations, the influence of the structure dimensions and the dielectric parameters on dispersion characteristic and coupling impedance of this kind of slow - wave structure is obtained. then, the linear beam - wave interaction theories of the arbitrarily - shaped helical groove waveguide and the dielectric into the arbitrarily - shaped helical groove waveguide are deduced. by the numerical calculations, the relationship is got between the small signal gain, bandwidth, electromagnetic " hot " velocity and the electronic beam, the structural parameters

    通過數值計算，獲得了此類慢波結構的色散特性和耦合阻抗隨結構幾何尺寸和介質參數的變化規律;在此基礎上，建立了任意槽形螺旋槽及中心加介質棒的任意槽形螺旋槽行波管的注-波互作用線性理論，並編製程序，計算了管子的小信號增益、帶寬、電磁慢波的「熱」相速與電子注參數、結構參數之間的關系，獲得了增加帶寬或增益的途徑。
