Analysis of the complex radiating objects by using hybrid FDTD/MoM - PO method
Języki publikacji
Abstrakty
W artykule przedstawiono hybrydową metodę analizy złożonych obiektów promieniujących i/lub rozpraszających fale elektromagnetyczne. Omówione podejście łączy w sobie zalety dwóch konwencjonalnych metod pełnofalowych: metody momentów (MoM) i metody FDTD. W celu zwiększenia efektywności analizy obiektów dużych elektrycznie metodę momentów połączono dodatkowo z asymptotycznym przybliżeniem optyki fizycznej (PO). Skuteczność proponowanego podejścia hybrydowego (FDTD/MoM - PO) pokazano na przykładzie analizy anteny reflektorowej.
In this paper, the FDTD/MoM - PO hybrid technique is presented. The proposed approach is applied to complex electromagnetic problems such as those involving antennas radiating in the presence of dielectric bodies. The method combines the ability of the FDTD method to deal with arbitrary material properties, and versatility of the MoM - PO method for conducting structures. Numerical results show that the FDTD/MoM - PO hybrid technique offers a noticeable memory and CPU time saving.
