Abstract

This paper presents a new simulation strategy based on the hybridization of a full wave time domain multi-scale method, the Dual-Grid FDTD (DG-FDTD), and the Physical Optics (PO). This new method aims at simulating antennas mounted on large conducting platforms and whose nearby surrounding environment is very complex. Typical application fields of the hybrid DG-FDTD/PO method are the computation of radiation patterns of antennas mounted on carriers such as satellites, ships, aircraft and land vehicules.
