| 摘 要： | 为了解决单轴各向异性吸波涂层(UARAC)的分析和设计中所遇到的反射系数计算问题,从电磁场理论出发,导出了电磁波以任意角入射时UARAC的反射系数公式。同时,给出了计算曲线的例子,通过实例计算分析了UARAC的斜入射特性和电磁波的入射角、极化状态等对UARAC的隐身效果的影响。得到负单轴各向异性吸波涂层(MUARAC)的吸波性能优于正单轴各向异性吸波涂层(PUARAC)的吸波性能及MUARAC的吸波性能主要取决于单轴各向异性吸波材料的横向参数等结论。为UARAC的计算机辅助分析和设计提供了基础。

| Abstract: | For the design and analysis of the uniaxial anisotropic radar absorbing coat(UARAC),the formulae of computing its reflecting coefficient are derived from the theory of electromagnetic field for incident electromagnetic waves.The examples of calculated curves are presented.The reflection characteristics of UARAC for oblique incidence waves and the influences of incident angle and polarization state on the stealth effect of UARAC are analyzed by means of numerical calculation.Such conclusions are drawn that the minus uniaxial anisotropic radar absorbing coat(MUARAC) has better performance in absorption than the plus uniaxial anisotropic radar absorbing coat(PUARAC),and the absorption performance of MUARAC is determined principally by the transverse parameters of uniaxial anisotropic radar absorbing material.The analysis made in this paper can provide a basis for CAA and CAD of UARAC composition. |
