“…The above procedure can be extended by requiring that the macromodel mimics the behavior of the structure for different configurations of a set of design or physical parameters, whose value is not fixed a priori but is known to belong to a prescribed set. In such a case, the network function data are sampled in correspondence of a finite number of parameters configurations, and a multivariate modeling strategy is pursued to obtain a parameterized macromodel that can replace the original structure for all of the parameters configurations of interest [11]- [15].…”

“…An original large‐scale circuit or system is first characterized, leading to some first‐principle description of its behavior. This can be in form of partial differential equations or integral equations (PDEs and IEs, e.g., as resulting from Maxwell full‐wave formulations), ordinary differential equations (ODEs) or differential algebraic equations (DAEs), the latter being the common choice in circuit formulations based on the modified nodal analysis (MNA), or even in terms of time‐ 6 or frequency‐domain sampled responses 7–12 . The latter situation occurs when only direct measurements are available or alternatively when a nonintrusive solver is used to retrieve the system responses.…”

“…This paper presents a novel dissipativity characterization of LTI models in parameterized descriptor form 12 . The proposed formulation extends spectral characterizations of nonparameterized models based on the associated Hamiltonian matrix 14,20 to the bivariate case, allowing dependence of the transfer function on one external parameter in addition to frequency.…”
