Abstract

Abstract In this paper, the electromagnetic interference shielding effectiveness (EMI SE) of multilayer graphene films is studied by the Monte Carlo (MC) method. First, we use the transfer matrix method to study the transmission and reflection of electric fields of the incident light passing through the graphene plane and the dielectric interface, and then determine the reflection and transmission probability of the light. In this way, the path of light can be obtained by the MC method. From the distance and emission direction of a large number of lights passing through the film, the expected value of the emitted light field is calculated and the EMI SE is determined. The obtained results of SE are shown to be in good agreement with several sets of experimental data. This model also takes into account the influence of wrinkles of graphene. It is found that EMI SE first increases and then decreases with the increase of wrinkle. The effects of film thickness, conductivity, and dielectric constant on EMI SE in the X-band frequency range are also investigated.
