Outline of Final Research Achievements

The electromagnetic shielding interference (EMI) materials based on carbon nanotube is focused, and the high performance electromagnetic materials are developed by using nano-technology. The strong magnetic porous complex particles, strong dielectric nanotubes, period structures with dielectric property for electromagnetic shielding are fabricated successfully. Based on these results, design freedom of electromagnetic shielding products will be leveled up greatly, which will be benefit for the products development of information and high shielding fields. Furthermore, with a three-dimensional design of dielectric materials, it is possible to develop a specified frequency of EMI materials. The EMI waves could be clarified to be surface reflection, inner absorption and multi- reflections on the interface, corresponding to each component, some of EMI mechanism is made clear.
