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 transmission spectroscopy and millimeter wave reflection cross section and transmittance method were used to study the electromagnetic wave attenuation performance of water-based foam. Experimental studies have found that a small amount of foam can lead to smaller infrared 3-5 μm, 8-14 μm and 8 mm wave transmittance: the infrared extinction coefficient in the range of 3-5 μm is more than 75% greater than 1.0 m 2 · g -1, The infrared extinction coefficients of 14μm band are all larger than 0.6m2 · g-1. The average RCS of 8mm wave radar is about 0.3029m2. Foam has a good decay and special structure, plus its water-soluble, easy to mix, good rheological and economic advantages, it can be considered: water-based foam is a great potential for research and development of new broadband passive optical Interference media.
