A new jamming technology of atomized screen was studied to overcome the shortcomings of existing broad band jamming technology, such as the short acting time and the narrow jamming wave band. The theory of multiband jamming and the formula of atomized screen was introduced. The jamming effect on multiband such as visible light, laser, infrared, millimeter wave radar and centimeter wave radar has been tested. Necessary theory and experimental data were provided for the application of this technology. The experimental results show that visible light and laser could be shielded when the foam diameter of atomized screen was 2-3 mm and the thickness was 50 cm. Under the same conditions, the transmission of infrared was less than 5％, and the good screening effect was achieved on millimeter wave radar and centimeter wave radar. The high efficiency interfering time was above 20 min. The study shows that the new atomized screen was a potential wide frequency passive interfering medium.
