Linearization of Parametric FIT-Discretized Systems for Model Order Reduction

Electrodynamic field simulations typically require the solution of large linear systems which may depend on several variables. Model Order Reduction Techniques offer an approach to solve these multivariate problems in a reasonable time. This paper presents an Order Reduction Method and the required system equation linearization for structures discretized by the Finite Integration Technique (FIT) depending on frequency and length variation.
