Guaranteed passive parameterized macromodeling by using sylvester state-space realizations Vrije Universiteit Brussel Ghent University
A novel state-space realization for parameterized macromodeling is proposed in this paper. A judicious choice of the state-space realization is required in order to account for the assumed smoothness of the state-space matrices with respect to the design parameters. This technique is used in combination with suitable interpolation schemes to interpolate a set of state-space matrices, and hence the poles and residues indirectly, in order to ...

Parametric macromodeling for S-parameter data based on internal nonexpansivity Vrije Universiteit Brussel Ghent University
We propose a novel parametric macromodeling method for systems described by scattering parameters, which depend on multiple design variables such as geometrical layout or substrate features. The new concept of internal nonexpansivity for bounded real systems is introduced. It is used in combination with suitable interpolation schemes to interpolate a set of state-space matrices, and hence poles and residues indirectly, to build accurate ...
Parametric macromodeling based on amplitude and frequency scaled systems with guaranteed passivity Vrije Universiteit Brussel Ghent University
We propose a novel parametric macromodeling method for systems described by scattering parameters, which depend on multiple design variables such as geometrical layout or substrate features. It is able to build accurate multivariate macromodels that are stable and passive over the entire design space. Poles and residues are parameterized indirectly. The proposed method is based on an efficient and reliable combination of rational ...

Compact and passive parametric macromodeling using reference macromodels and positive interpolation operators Vrije Universiteit Brussel Ghent University
We present an enhanced parametric macromodeling method that is able to generate compact and passive models over the entire design space of interest. It starts from a discrete set of data samples of the input-output system behavior (e.g., admittance, impedance, and scattering parameters), which depend on multiple design variables such as layout and substrate parameters. The proposed approach generates accurate parametric macromodels whose size ...
Passivity-preserving parametric macromodeling by means of scaled and shifted state-space systems Vrije Universiteit Brussel Ghent University
We propose a novel parametric macromodeling method for systems described by admittance and impedance representations, which depend on multiple design variables such as geometrical layout or substrate features. It is able to build accurate multivariate macromodels that are stable and passive over the entire design space. Poles and residues are parameterized indirectly. The proposed method is based on an efficient and reliable combination of ...
Parametric macromodeling for sensitivity responses from tabulated data Vrije Universiteit Brussel Ghent University
This letter presents a parametric macromodeling technique which accurately describes the parameterized frequency behavior of electromagnetic systems and their corresponding parameterized sensitivity responses with respect to design parameters. The technique is based on the interpolation of a set of state-space matrices with a proper choice of the interpolation scheme, so that parametric sensitivity macromodels can be computed. Pertinent ...
Passivity-preserving parametric macromodeling for highly dynamic tabulated data based on lur'e equations Vrije Universiteit Brussel Ghent University
We present a new method for the construction of parametric macromodels for admittance and impedance input- output representations starting from multivariate data samples that depend on frequency and additional design variables such as geometric and material parameters. Poles and residues are parameterized indirectly, while stability and passivity of the parametric macromodel are guaranteed over a user defined range of design parameter values. ...
