在厘米波段,当微粒尺寸小于入射波波长时,利用双层球形颗粒的Mie散射理论,研究了双层球形结构的电磁波散射和吸收特性,结果显示内核为磁性材料的双层球微粒,其吸波能力和隐身性能都优于内核为非磁性材料的双层球微粒。在此基础上,数值计算了内层是碳或铁介质,外层为非磁性等离子体的包覆体新型结构,结果表明该结构具有很好的电磁波衰减和吸收特性。
In the centimeter band, when the particle size is smaller than the wavelength of the incident wave, the electromagnetic scattering and absorption characteristics of the double-layer spherical structure are studied by using the Mie scattering theory of double-layer spherical particles. The results show that the inner core is a double layer spherical particle of magnetic material, Wave power and stealth performance are better than the core of the non-magnetic materials, double-layer ball particles. On this basis, the new structure of the coating of the non-magnetic plasma is calculated by numerical calculation of the inner layer of carbon or iron, the results show that the structure has good attenuation and absorption characteristics of electromagnetic waves.
