Abstract-An efficient wide-band analysis that combines modified integral equation-physical optics (IE-PO) hybrid formulation with the best uniform approximation is proposed for antennas around an electrically large platform in this paper. The modified single-level Fast Fourier Transform (FFT) algorithm which is based on the subdomain FFT acceleration is employed by interpolating the Green's function and introducing the concept of the empty groups. Furthermore, the correction of the nearinteraction is avoided. On the other hand, the best uniform approximation technique is applied to analyze wide-band properties of antennas. Due to the above modifications, the hybrid method needs fewer unknowns and memory requirements than the conventional one.

-This paper presents a new simulation strategy based on the hybridization of a full wave time domain multi-scale method, the DualGrid 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.

“…The approaches proposed in [15][16][17][18][19] treat smooth region of PEC objects with the P O method, and its remaining part by the MoM. On the other hand, several techniques have also been proposed for mirroring the frequencydomain current-based hybrid methods into the time domain, with an extension of hybridization as demonstrated in [20,21] and MOT scheme implemented.…”

Abstract-An efficient and stable hybrid method, based on the time-domain integral equation (TDIE) and time-domain physical optics (TDPO), is developed for investigating transient radiation and scattering from perfectly electrical conducting (PEC) objects. It at first requires partitioning the PEC object surface into TDIE and TDPO regions, respectively. Then, a set of hybrid TDIE-TDPO equations is derived and solved using an adaptive marching-on-indegree (MOD) method. The fast Fourier transforms (FFT)-based blocking scheme is further implemented into the proposed algorithm so as to reduce N 2 O dependence of the traditional MOD method to N O log 2 (N O ), where N O is the highest order of the weighted Laguerre polynomials used for computation. Under such circumstances, its computational cost, in comparison with the full TDIE-MOD solver, is reduced significantly. Several numerical examples are presented to demonstrate its accuracy and efficiency in solving some typical transient electromagnetic problems.
