研究了非均匀介质的耦合指数传输线,并且得到了精确的解。其解已成功地应用于微波定向耦合器的设计中。与使用均匀传输线的耦合器相比较,在耦合特性方面指数线耦合器有许多改进。实际测量结果与理论值非常一致。
The coupled exponential transmission line of inhomogeneous media is studied and an exact solution is obtained. The solution has been successfully used in the design of microwave directional couplers. There are many enhancements to exponential line couplers in terms of coupling characteristics as compared to couplers using even transmission lines. The actual measurement results and the theoretical value is very consistent.
