“…High-pressure water mist generated by high-pressure water jet technology is a new broad-spectrum electro-optic jamming material, which has a strong obscuring and jamming effect on infrared light, laser, radar and millimeter waves [1][2][3] . Ordinary water after slight filtration can serve as a jamming medium with low cost and pollution.…”

Abstract. The paper first elaborate the composition principle of the electro-optic obscuring system of high-pressure water mist. Then, the design principle of the system's core component -pulsed eddy current nozzle is introduced. Finally, the obscuring effect of the system is verified through the infrared thermal imaging experiment. The experimental results show that high-pressure water mist generated by the system can greatly reduce the infrared signature of objects to be obscured with significant electro-optic obscuring effect. The system can be used for homeland defense with high practical value.

In this study, the thermal shielding ability of sprays and the accompanying scientific problem of the optimal extinction diameter of moving droplets have been analyzed with the Lagrangian model and Mie theory under the overall consideration of dynamical and optical characteristics. A correction factor is introduced to eliminate the forward scattering effects of large droplets. Then, a new variable, named the thermal shielding index, has been presented as a criterion evaluating the extinction abilities of moving droplets, which analyzed the extinction performance during the whole lifetime of droplets. According to the evaluation method defined in this paper, the optimal extinction diameters obtained based on the thermal shielding index are far greater than those obtained based on the optical properties. In addition, if the initial droplet sizes were relatively large, the upward injection way will perform better than the downward injection way for a longer traveling distance and, of course, a longer lifetime.
