Abstract
Recently, the design of low cost, lightweight, and flexible electromagnetic interference (EMI) shielding fabrics mitigation is a great issue, and are required for a variety of defense, wireless power transfer (WPT), and medical applications.

and Cobalt Co Nano-particle laminate epoxy films that simultaneously exhibit a good electrical conductivity, and a high level of EMI shielding in the 'E, F, I, and J' band frequency. In this paper, we propose a coupling mechanism with an alternate-layer shielding structure by presenting a process for scalable composition of laminate epoxy hybrid composites with high content of CF/GF/Co–TiO

, and report on the EMI shielding effectiveness (SE) and electrical properties of hybrid laminate composites. An experimental stand was built to evaluate the total transmitted efficiency and SE of the proposed laminate composite. The experimental results show that the alternate layers of shielding laminate could effectively enhance the EMI SE and transmit power of the order under the working environment with poor coupling through improving the stability of the system. We expect that the design directions prophesy by our model provide the basis for future works in which higher levels of EMI shielding efficiency may be accomplished using alternative fabrication techniques.
