Abstract :
We present a new parametric macromodeling technique for admittance and impedance input-output representations parameterized by design variables such as geometric and material parameters. Stability and passivity of the parametric macromodel are guaranteed over a user defined range of design parameter values, while poles and residues are parameterized indirectly. Numerical results validate the proposed parametric macromodeling approach.
