摘　　要：虽然椭圆波导已经在卫星通信和雷达馈线等方面得到了应用,然而在已往文献中,椭圆波导中没有一个模的场图是通过解析方法绘出的.本文给出了两种不同偏心率的椭圆波导中cE_01模的级数解析表示式,并绘出了它们的场图.本文求解矢量场的方法是严格的和标准的.这个模的电场线和磁场线确实和Chu绘出的不同,他的场线是错误的.Although elliptic waveguides have already been used in several fields such as satellite communication and radar feed lines, none of the field patterns in elliptic waveguide has been plotted accurately in terms of analytic method in the past litratures. In this paper,the analytic expressions in series for the field components of the cE01 mode in elliptic guide with two different eccentricities are given. The field patterns of this mode are plotted. This method for solving vector fields is exact and standard. The lines of electric and magnetic field are indeed different from those by Chu. The latter's patterns are incorrect.
