本文推导出了非均匀介质中耦合指数传输线散射参数的精确公式。这些公式可用于设计宽带定向耦合器。对所设计的耦合器的实际测试证明推导出来的公式是正确的。
This paper deduces the exact formula of the scattering parameters of the coupled exponential transmission line in inhomogeneous media. These formulas can be used to design broadband directional couplers. The actual test of the coupler designed proves that the formula is correct.
