Abstract :
In this paper an efficient method for fast eigen-analysis of waveguide structures over a wide frequency band is presented. The procedure applies a multidimensional subspace method based on singular value decomposition to perform parametric model order reduction directly on the finite element eigenvalue equations. Numerical example of a microstrip line is provided to illustrate the validity of the proposed method.
