Abstract

The asymptotic waveform evaluation (AWE) technique has been widely used for handling the fast parameter sweep. However, how to determine the sweep bandwidth is still an open question. This work proposes an efficient and flexible bandwidth estimation approach. This approach also naturally leads to an efficient multipoint AWE technique. The validity of the proposed approach is verified by numerical experiments on the AWE-incorporated hybrid finite element/boundary integral (FE/BI) method for scattering problem. Numerical experiments show that this approach can greatly improve the efficiency and practical capability of the AWE technique.
