摘要
研究了一种通过立体编织和金属化纤维掺杂获得的三维立体布面结构,对其在3 mm和8 mm波段的毫米波衰减性能进行测试研究,并根据电磁波Mie散射和吸收理论进行分析。实验结果表明,这种立体布面结构通过散射和吸收的双重作用,可有效衰减毫米波回波信号,并且其衰减特性符合电磁波Mie散射和吸收理论。
A three-dimensional fabric structure attained by three-dimensional fabricating and metal- ized fiber doping is researched. Its millimeter attenuation characteristics in 3 mm and 8 mm are tested and re- searched. And the characteristics are analyzed according to Mie scattering in electromagnetic wave and ab- sorption theory. Experimental results show that echo signals in millimeter wave can be attenuated effective- ly by double actions of scattering and absorbing from the three-dimensional fabric structure. And the attenu- ation characteristics are in accordance with Mie scattering in electromagnetic wave and absorption theory.
