摘要 进气道等腔体结构是飞行器的强散射源之一,在腔体内表面涂覆吸波涂料可以有效地减缩其雷达散射截面(RCS),应用等效表面阻抗边界结合迭代物理光学法能够高效、快速计算涂覆有损耗材料腔体的散射特性,进而对吸波涂料的电磁参数和涂覆部位进行比较优化。计算结果表明计算方法是正确有效的。 The cavities such as jet engine inlets have a significant impact on the overall signature of the airplane structure. The RCS can be efficiently reduced by coating dielectric material on the inner surface of cavity. An equivalent surface impedance boundary condition (EIBC) combined with the iterative physical optics is used to compute the scatterinmg of the three-dimensional electrically large cavity. The numerical results indicated that the hybrid method is efficient.
