摘要:
A simple circuit model for the multistrip coupler is presented. The transmission matrix of a single strip relating the output‐ and input‐wave amplitudes in different tracks is obtained from circuit theory. The overall transmission matrix of the coupler is obtained by cascading the transmission matrices of successive strips. The model is shown to yield the correct results for common coupler configurations. This model because of its strip‐by‐strip approach makes it straightforward to analyze nonperiodic couplers which are difficult to analyze by usual techniques. Numerical solutions for a strip‐coupled UDT are presented in agreement with previous experimental results.
