Parameterized sensitivity analysis of multiport systems by means of the partial element equivalent circuit method and interpolation schemes

This paper presents a new methodology to perform parameterized sensitivity analysis based on the electromagnetic method called Partial Element Equivalent Circuit. The proposed methodology is based on the multivariate interpolation of the matrices produced by the electromagnetic solver, which are initially computed at a set of design space points. The proposed interpolation scheme is able to compute the derivatives of the electromagnetic matrices, which are needed to perform the sensitivity analysis. Pertinent numerical results are shown to prove the robustness of the proposed methodology.
