纤维布层板吸波材料的等效电磁参数

Equivalent EM Parameters of Fiber Cloth Sheet Absorbing Material

提出了一种预测广泛应用于制造隐身飞行器的吸波纤维布层板等效介电常数和磁导率的方法。纤维布层板等效电磁参数是设计中重要的数据。考虑到结构的各向异性，利用强扰动理论推导出了求解电磁参数的复数型积分方程组，用Ｆｏｒｔｒａｎ５．１设计了系统软件进行迭代法搜索求解。并列举了预测等效电磁参数的实例。

A method for preestimating the equivalent electromagnetic parameters of absorbing fiber cloth sheet which has been widely used in fabricating stealth vehicles is presented.The equivalent EM parameters(i.e.,permittivity and permeability)are the most important data in design.With the anisotropic property structure of the mixed media,based on the strong fluctuation theory,a set of complex integral equations for EM parameters are formulated.With Fortran 5.1,a system software is set up to search out these unknown parameters by iterative way.Some preestimating EM parameters examples are listed.
