椭圆锥带线的严格解

Exact Solution of Elliptic Cone Stripline

研究了椭圆锥带线的特性阻抗等基本参数。假设中心导体带是无限薄理想导体，传输的是TEM模，通过坐标变换和共形映射，把椭圆锥带线变为有限宽平行板带线。应用椭圆积分变换得到了椭圆锥带线参数的严格解。该方法可用于圆柱、椭圆柱、圆锥和椭圆锥问题的求解。

The exact solution of the elliptic cone stripline is derived based on the TEM mode and perfect conductor assumptions. Using the coordinate transform and conformal mapping technique, the ellipilic cone stripline is transformed to a parallel plate stripline. The basic parameters including the characteristic impedance, effective dielectric constant and capacidance per unit length are obtained using elliptic integral transform. The method used in this paper is useful for the problems of circular, elliptic cylinders and circular, elliptic cones.
