摘要: 本文由Meleontiev方法将任意复杂形状的单连通区域的外部变换为单位圆的外部,利用多项式变换函数的性质和复杂形状内导体边界的等效圆半径变化的一般规律,给出了具有圆形外导体-复杂形状内导体一类传输线的解。通过与文献中准确值的比较,证实了本文方法的准确性和实用性。Abstract: In this paper, the transformation of an exterior of a simply-connected region into an exterior of a unit circle is made by Melentiev s method and a formula is presented for determining the characteristic impedance of a coaxial transmission line consisting of a circular outer conductor and an irregular inner conductor. The validity of the formula is confirmed by numerical results.
