Pade via Arnoldi with single-size matrix simplification for electromagnetic fast frequency sweep

摘要

This paper proposes a new Pade via Arnoldi algorithm with single-size matrix simplification for electromagnetic (EM) fast frequency sweep. New equations are derived to reduce the double-size system matrix to single-size system matrix. We also propose a systematic algorithm to calculate S-parameters using the simplified single-size system matrix. Using the proposed algorithm, the EM responses can be obtained with the same accuracy while consuming much less time compared with that using the existing double-size matrix Pade via Lanczos. The proposed algorithm is demonstrated by two microwave examples.
