Effect of Hollow Structure on the Electromagnetic Interfering (EMI) Shielding of Aluminum-Cenospheres Composites
The electromagnetic interference shielding effectiveness (EMISE) properties are measured using coaxial cable method in the frequency range of 10 -1200MHz. EMI analysis indicates EMISE properties of these three types of composites is mainly influenced by the hollow structure of cenospheres, suggesting the common effects of reflection and multiple reflections mechanisms. On the other hand, the change of matrix from pure aluminum (1199) to aluminum alloy (2024) on EMISE properties can be negligible.
