THE SOLUTION OF THE CHARACTERISTIC IMPEDANCE OF ARBITRARILY SHAPED COAXIAL TRANSMISSION LINES BY USING THE OPTIMIZED SIMULATED IMAGE-CONFORMAL MAPPING METHOD
结合保角变换的优化模拟镜象法解多种截面形状同轴线的特性阻抗

A new method, the optimized simulated image method in combination with conformal mapping, is introduced to calculate the characteristic impedance of arbitrarily shaped coaxial transmission lines. It is of small calculating amount and high accuracy, and the error range can also be estimated. The calculating results of the characteristic impedances of nine coaxial lines, such as concentric, eccentric circular inner and square outer conductors, strip inner and circular outer conductors, are tabulated and compared with data from other papers.
