Abstract

A Loewner matrix data-driven model order reduction technique for fast frequency sweep in full-wave solution in large finite frequency selective surfaces is detailed. A hybrid Boundary Integral-Finite Element Domain Decomposition Method is addressed to accurately predict the electromagnetic behavior of these structures. A reduced-order model is built up by means of simulation scatering parameters. A Loewner matrix approach is taken into account to provide a tangential interpolation to output data. As a result, a dynamical system representation fitting the simulation data is obtained, and further electromagnetic insight can be obtained from this system representation.
