摘要

基于全波分析研究了非完全导电带状传输线的准瞬变电磁法特性阻抗。通过满足表面阻抗边界条件的并矢格林函数来适应带状线外导体不完美的影响。通过使用电阻片边界条件来容纳中心导体的不完美，并导致准瞬变电磁法条带电流的EFIE公式。该中心条带电流随后允许计算准瞬变电磁法特性阻抗。研究了有限电导率对准瞬变电磁法特性阻抗的影响。讨论了这些结果在未来应用中的重要性。

Full-wave Quasi-TEM characteristic impedance of an imperfectly-conducting strip transmission line

The quasi-TEM characteristic impedance of an imperfectly-conducting strip transmission line based on a full-wave analysis is investigated. The effect of the imperfect outer conductors of the stripline are accommodated via a dyadic Green's function satisfying surface impedance boundary conditions. The imperfect center conductor is accommodated through the use of a resistive sheet boundary condition and leads to an EFIE formulation for the quasi-TEM strip current. This center strip current subsequently allows computation of the quasi-TEM characteristic impedance. The effect that finite conductivity has on the quasi-TEM characteristic impedance is investigated. The importance of these results for use in future applications is discussed.
