摘要
本文解决了平面波入射时涂覆各向异性复合手征介质的阻抗圆柱体的电磁散射问题。首先推导得到各向异性复合手征介质层中电磁场量的基本方程;然后根据边界条件得出计算所讨论的阻抗圆柱体的雷达散射截面的解析表达式。文中还给出若干数值结果。
The problem of scattering of a plane electromagnetic wave incident on an impedance conducting cylinder cladded with a composite and anisotropic chiral medium sheath is solved. The formulas for calculating the electromagnetic fields in composite and anisotropic chiral media are derived. An analytic expression for the radar cross-section of an impedance cylinder coated with composite and anisotropic. chiral material is obtained by application of boundary conditions. Several typical results are also presented.
