Full-wave Modeling Using Curvilinear Surface and Volume Meshes for the Calculation of Radar Scattering from Material Coated Targets

Abstract

A hybrid surface and volume integral equation approach is implemented for the calculation of electromagnetic scattering from dielectric material coated complex targets. The implementation includes three sets of mesh types: triangle/tetrahedron, quadrangle/hexahedron of first order, and quadrangle/hexahedron of second order (curvilinear). The solver is accelerated by the multilevel fast multipole algorithm so that electrically large sized targets can be analyzed. The program can be used for RCS analysis of complex targets, antenna-platform interaction calculation, wave propagation simulation, and microwave circuit analysis.
