摘要
本文介绍一种在时域有限差分（ＦＤＴＤ）算法中薄涂层介质参数的等效处理方法。具体计算例子表明这种方法对处理金属表面涂层厚度不到一个ＦＤＴＤ元胞大小的情况非常有效。最后还计算了有耗涂层飞机机翼模型的ＲＣＳ。
Based on the Approximate Boundary Condition for a metal-backed layer proposed by senior,an equivalent impedance method is introduced for FDTD computation when the thickness of coverage on a perfectly conducting object is less than the dimension of an FDTD cell.The feasibility of this method is exemplified and the RCS of coated airfoil model is evaluated.
