Abstract

An electromagnetic in-house parallel EM solver for RCS computation of complex target is presented in this paper. The solver makes use of a weak formulation based on double curl vector wave equation discretized with the higher-order isoparametric curl-conforming tetrahedral finite element rigorous implementations of Nédélec first family of elements. For RCS analysis, a non-standard mesh truncation technique, FE-IIEE (Finite Element - Iterative Integral Equation Evaluation) is used providing an arbitrarily exact absorbing boundary condition while retaining the original sparse structure of the FEM matrices. A numerical example is presented showing the reliability, performance, and versatility of the FEM solver for RCS computation.
