An extension of the generalized Hamiltonian method to S-parameter descriptor systems

Abstract-- A generalized Hamiltonian method (GHM) was recently proposed for the passivity test of hybrid descriptor systems [1]. This paper extends the GHM theory to its S-parameter counterpart. Based on the S-parameter GHM, a passivity test flow is proposed, which is capable of detecting nonpassive regions of descriptor-form physical models. The proposed method is applicable to S-parameter and hybrid systems either in the standard state-space or descriptor forms. Experimental results confirm the effectiveness and accuracy of the proposed method.
