摘要
采用傅里叶变换红外透射光谱法和毫米波反射截面及透射率法,研究了水基泡沫的电磁波衰减性能。试验研究发现,少量的泡沫即可导致较小的红外3~5μm、8~14μm波段和8mm波透过率:3~5μm波段红外消光系数75%以上大于1.0m2·g-1,而8~14μm波段红外消光系数均大于0.6m2·g-1;8mm波雷达反射截面积(RCS)平均约为0.3029m2。泡沫具有良好的衰减性和特殊结构,加立其水溶性、易配性、良好的流变性和经济性等优点,可以认为:水基泡沫是一种极具研究潜力的新型宽波段无源光电干扰介质。
Fourier-transform-infrared (FTIR) and millimeter wave(MMW)are applied to study the electromagnetic waves attenuation by the aqueous foams.Low transmission was found at 3-5 μm,8-14 μm and structure besides the species and its consistency play main pole of the nice attenuation.And the further performances virtues of water-solubility, adjustability,nice rheology and inexpensive make US believe that foam is a novel nice potential medium of broadband PPECM.
