Multivariate finite element model order reduction for permittivity or permeability estimation

An efficient finite element method for the analysis of passive microwave components over wide ranges of frequencies and material parameters is proposed. First, a parameterized equation system of low order is generated, which is then solved for specific parameter values. Since the evaluation of the reduced order system is very fast, the proposed method is very well-suited as a forward solver for permittivity or permeability estimation
