摘要 采用新的方法推导出非均匀介质中非对称耦合传输线的传输矩阵 (T参数 )解析表达式 ,给出了以正规模式参量描述的 T参数表达式。所得 T参数表达式形式简明 ,物理概念明晰。通过矩阵分块运算 ,由散射参数推导 T参数 ,对所给表达式进行了验证。验证结果表明所得 T参数解析表达式的正确性和方法的有效性。 T参数解析表达式的导出为非均匀介质中非对称耦合传输线在三维 (多层 )微波集成电路中的应用提供了有力的理论工具。 Using a novel approach, the analytic expressions of the chain scattering parameters ( T -parameters) for the asymmetric coupled transmission lines in inhomogeneous medium (ACTLIM) are derived in this paper for the first time. The expressions of the T -parameters for the ACTLIM expressed by normal mode parameters are given. The expressions of the T -parameters are explicit in the form and clear in the conception. Using the matrix operation, the presented expressions have been approved by results derived from the S-matrix. The T -parameters of the ACTLIM given in the paper will provide powerful theoretical tool for the application of the ACTLIM in the three dimensional (multilayer) microwave integrated circuits.
