The method of conformal mapping is a tool to achieve this solution. 保角映射法就是一種尋求這個解的工具。
This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance. 這種方法是採用兩次保角變換結合同軸線特性阻抗公式進行特性阻抗計算。
Classical complex variable method is followed, but a new conformal mapping formula is proposed so that the exterior part of the parabolic crack is mapped into a unit circle. 採用了傳統的複變函數保角映射法，給出了一個新的保角變換公式，從而將拋物線曲裂紋外的區域映射到一個複平面的單位圓內。
