摘要
对阻抗边界条件(IBC)进行了适当的修正,拓宽了其应用的范围。利用修正后的IBC 条件和 Fock 理论以及物理光学(PO)近似,导出了二维大尺寸涂层及无涂层导电目标散射宽度(EW)的计算公式。通过数值计算和比较,Fock/PO 解可以给出令人满意的结果。
Impedance boundary condition(IBC)is modified to extend the scope of its ap-plication.Formulas for calculating the echo width(EW)of a two-dimensional coated oruncoated conducting body of large size are derived by using the modified IBC,Fock theoryand physical optics(PO)approximation.Through numerical calculation and comparison,itis seen that Fock/PO solutions present quite satisfactory results.
