摘　　要：该文提出了用于计算具有圆形外导体复杂形状内导体的一类传输线特征阻抗的分数阶多极子模 型。该方法能够很好地处理导体棱角附近电位梯度的奇异性问题。通过具体算例证明了该方法的实用性.The model of fractional multipole is presented for calculating the characteristic impedance of coaxial transmission line with circular outer conductor and complex inner conductor. The model has a higher accuracy in analyzing the potential of a point close to a sharp conducting edge. The validity of this model is confirmed by numerical results.
