✦ Synopsis

Model order reduction of an electromagnetic system is understood as the approximation of a continuous or discrete model of the system by one of substantially lower order, yet capable of capturing the electromagnetic behaviour of the original one with su$cient engineering accuracy. Model order reduction technqiues are reviewed and critically examined in this paper. The emphasis is on techniques suitable for the generation of high-order PadeH approximations to transfer functions of electromagnetic systems discretized using "nite methods. The computational complexity associated with the application of such model order reduction techniques to electromagnetic systems of practical interest is discussed, and the computationally most e$cient model order reduction algorithm is identi"ed. The bene"ts of model order reduction are demonstrated through a series of numerical examples from the analysis of electromagnetic waveguides.

## Abstract Many different techniques to reduce the dimensions of a model have been proposed in the near past. Krylov subspace methods are relatively cheap, but generate non‐optimal models. In this paper a combination of Krylov subspace methods and orthonormal vector fitting (OVF) is proposed. In t

## Abstract This paper explores some numerical alternatives that can be exploited to derive efficient low‐order models of the Navier–Stokes equations. It is shown that an optimal solution sampling can be derived using appropriate norms of the Navier–Stokes residuals. Then the classical Galerkin app
