Domain Decomposition Method Using Integral Equations and Adaptive Cross Approximation IE-ACA-DDM for Studying Antenna Radiation and Wave Scattering From Large Metallic Platforms

A Novel JMCFIE-DDM for Analysis of EM Scattering and Radiation by Composite Objects

“…which is essentially the TC developed in [9]. In this regard, the proposed TC can be viewed as a generalization of [9] for composite objects.…”

“…(9). In doing this, rows of zeros in the final linear system can be totally avoided, results in a better condition of the final DDM system.…”

“…The basic idea of DDM is to replace the global boundary value problem by several easily-manageable local boundary value problems, with the aid of appropriate coupling or transmission conditions between sub-domain interfaces [2]- [9]. Generally, SIE-DDM can be classified into two categories: surface-based SIE-DDM, and volume-based SIE-DDM.…”

“…For example, an optimized second order TC is developed to improve the convergence of cavity scattering problems in [8]. In [9], Maurin et al proposed a new DDM formulation with a better condition number for conducting objects. In this method, the electric field integral equation (EFIE) coupling from the entire sub-domain are considered at the interfaces, in addition to the traditional implementation of Robin-type TCs.…”

“…In this letter, the method developed in [9] is further extended to model complex composite structures involving conductors and dielectrics. Both electric and magnetic field interactions are enforced at the interfaces, in addition to the traditional implementation of Robin-type TCs.…”
