摘要：

A novel strategy for the efficient analysis of frequency-domain scattering electromagnetic problems in open and closed domains is presented. A fully automatic model-order reduction technique, called the enhanced reduced-basis method, is applied to increase the efficiency of the hybrid approach, which combines the finite-element and mode-matching methods. The numerical tests show that the proposed algorithm yields reliable and highly accurate results, whereas the computational time is reduced by up to one order of the magnitude.
