We develop a silicon dioxide hollow material/polyimide composite film with a low dielectric constant of 2.8~3.0 and reduce the weight by 30％. After the metallization of the composite film, the mechanical properties are highly stable and the transmission loss of circuit can be reduced by 30％ at 28 and 38 GHz, which is beneficial to the applications of 5G technology.
Besides the 5G demands, we also develope a body kinetic energy recovery and environmental electromagnetic wave recovery device, which can self-charge and supply power. By Using machine learning prediction and clustering techniques to assist the experimental process, we can find the best parameters. In addition, we use distributed computing to speed up the computing process.
