Layer-oriented Integration Vector Element of Multilayer RAM

In electromagnetic scattering solution of multilayer radar absorbing material (RAM), RAM is divided into multilayer thin elements under precise requirement, but quantity of elements grows too excessive to solve. In order to reduce solution scale, we develop layer-oriented integration arithmetic, and apply it into curve quadrilateral vector element. The core of this arithmetic is monolayer integral strategy of multilayer elements. In this paper, we solve electromagnetic scattering of multilayer RAM with layer-oriented integration vector element for presenting the arithmetic process. Numerical examples show that the layer-oriented integration vector element is high precise and applicable for multilayer thin structures electromagnetic computation.
