【摘要】 吸波材料通过把电磁波转化为其它形式的能量来降低目标的雷达散射截面,从而实现目标隐身的目的。频率选择表面(FSS)是一种具有二维周期性结构的滤波结构,主要在滤波器上使用。在总结了吸波材料作用原理和FSS结构分析方法的基础上,介绍了FSS结构和吸波材料复合构成的隐身技术的研究进展。更多还原

【Abstract】 Radar absorbing material could realize the stealth of aircraft through transforming the electromagnetic wave into other state of energy in order to reduce the radar cross section of aircraft. Frequency selective surface (FSS) is a two-dimensional periodical structure and used mostly in the filter. On the basis of the summarization of the principle of radar absorbing material and the analysis method of FSS structure, the development of stealth technique compounding radar absorbing material and frequency selective surface is introduced in this paper.更多还原
