Abstract: 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. -
