Is model-order reduction viable for the broadband finite-element analysis ofelectrically large antenna arrays?

[摘要] Model-order reduction provides an efficient way of computing frequency sweepsfor finite-element models, because the dimension of the reduced-order systemdepends on the complexity of the frequency response rather than the size ofthe original model. For electrically large domains, however, theapplicability of such methods is unclear because the system response may bevery complicated. This paper provides a numerical study of the effects ofbandwidth, electrical size, and scan angle on the size and convergence of theROM, by considering linear antenna arrays. A mathematical model is proposedand validated against numerical experiments.
