| Abstract: | This article proposes a parameter extraction algorithm based on adaptive interpolation fitting. By adaptively inserting interpolation points within a given interval, the number of the sampling points in the extraction process can be greatly reduced, which makes the calculation more efficient. Furthermore, the effect of noise can be eliminated with the multipath characteristic of the algorithm. The specific algorithm flow is given in detail. And two microwave filter design examples verified the feasibility and effectiveness of the proposed algorithm. |
