Microwave Composite Absorbers Based on Barium Hexaferrite/Carbon Nanotubes for 0.01- 18 GHz Applications

摘要

Nano- and microstructured composite materials have opened a new era for multifunctional materials. In particular, barium hexaferrites and carbon nanotubes can be applied in order to improve electromagnetic properties in composites. Magnetic materials with a texture based on barium ferrite and carbon nanotubes were obtained. The electromagnetic properties of Z -hexaferrites / carbon nanotubes composites were measured at microwave frequencies. It was shown, that imaginary permeability of barium hexaferrites/carbon nanotubes multilayer composites with double texture is as much as that of an isotropic samples at regions 3.4 - 8.5 GHz and 7.1 - 11.6 GHz.
