摘要: 本文由Meleontiev方法將任意復(fù)雜形狀的單連通區(qū)域的外部變換為單位圓的外部,利用多項式變換函數(shù)的性質(zhì)和復(fù)雜形狀內(nèi)導(dǎo)體邊界的等效圓半徑變化的一般規(guī)律,給出了具有圓形外導(dǎo)體-復(fù)雜形狀內(nèi)導(dǎo)體一類傳輸線的解。通過與文獻(xiàn)中準(zhǔn)確值的比較,證實了本文方法的準(zhǔn)確性和實用性。

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. -
