Two-dimensional (2D) materials are promising but remain to be further investigated, with respect to their interesting usage in optoelectronic devices. These materials have far less than ideal absorption due to their thin thickness, limiting their deployment in practical optoelectronic applications. Graphene is a 2D material with honeycomb structure. Its unique and fantastic mechanical, physical electrical and optical properties make it to be an important industrial and economical material. In this work, a simple analysis is performed for the reflectance, transmittance, and absorption properties of multilayer thin film structures with graphene sandwiched in dielectric layers. Based on Maxwell's electromagnetic wave theory and coupled Fresnel equations, we investigate how to get maximum absorption for a proper choice of media and graphene layers. Query ID="Q2" Text="Kindly check the corresponding author's affiliation is correctly identified. Numerical results show this absorption is controlled with matching thicknesses of layers, number of graphene layers, wavelength and angle of incident electromagnetic wave.
