Abstract: In order to overcome the shortcomings of the existing multi-band interfering techniques, a new interfering technique using special foam screen was put forward. Its interfering mechanism, the selected chemicals and the process of reaction were studied, and a foam screen set with an ejector was developed. The test results show that when the diameter of air bladder is about 0.5 mm, the special foam screen with 2?4 cm in thickness can interfere IR, MMW, CMW and visible light, and its inter?fering time can last for more than 0.5 h. The remains of this foam screen has no pollution to environ?ment.
