Preparation And Electromagnetic Waves Attenuation Performances Of Infrared-Interfering Composite Smog

The infrared-interfering composite smog material is prepared by a heating and agitating device in aqueous solutions and then sprayed into a cloud chamber for six minutes to form smog using gas-water mixing spray system. The attenuation performances of the smog to visible light, 1.06 mu m laser, 3-5 mu m infrared and 8-14 mu m infrared are evaluated, and compared with those of other testing materials. The results show that the sprayed smog have the best attenuation performances and the longest interfering time to visible light, 1.06 mu m laser, 3-5 mu m infrared and 8-14 mu m infrared. Therefore, the infrared-interfering composite smog material in the form of aqueous solution is the new smoke obscurant materials that are environment-friendly and possess broad application prospects in some aspects such as visible light, laser and infrared countermeasures.
