Abstact An iterative strategy combining Kirchhoff approximation^(KA) with the hybrid finite element-boundary integral (FE-BI) method is presented in this paper to study the interactions between the inhomogeneous object and the underlying rough surface. KA is applied to study scattering from underlying rough surfaces, whereas FE-BI deals with scattering from the above target. Both two methods use updated...
An iterative strategy combining Kirchhoff Approximation (KA) with the hybrid finite element-boundary integral (FE-BI) method is employed in this paper to consider the interactions between the plasma coated target and the underlying rough sea surface. This hybrid FE-BI-KA scheme is an improved and generalized version of previous KA-MoM, whereas the newly presented technique can deal with inhomogeneous...
An approach to studying composite EM scattering from 2-D rough surface and half-buried 3-D target is proposed in this paper, from accurate geometry modeling to RCS analysis. First, two dimensional rough surface is simulated with spectral method, which then is converted into a continuous curved surface through inverse engineering. Target model and rough surface model are combined together to be a very...
A new iterative strategy combining analytical Kirchhoff Approximation (KA) with the powerful simulation tool finite elementboundary integral (FE-BI) method is presented in this paper to study the interactions between an object and the underlying rough surface. This hybrid FE-BI-KA scheme is an improved and generalized version of MOM-KA. Instead of using MOM, FE-BI is used to model scattering from...
