A fast increase in wireless communications, portable devices, and high-power transmission lines has made the environmental EM pollution a major concern for human health. The dense packing of the electronic components in the state-of-the-art 2D, 2.5D and 3D integrated systems and generation of high heat fluxes create an environment with elevated temperatures, which adversely affect the efficiency and stability of the EMI shielding.
In the recent work, a research team led by a distinguished professor Alexander A. Balandin and research professor Fariborz Kargar, Department of Electrical and Computer Engineering, University of California – Riverside (UCR), reported on the scalable synthesis of composites with graphene fillers, and testing their EMI shielding efficiency in the X-band (frequency range of 8.2 GHz – 12.4 GHz) and the extremely high frequency (EHF) band (frequency range of 220 GHz – 325 GHz). The examined frequency bands are pertinent to state-of-the-art and future communication systems.
