Description
Summary:The significance of light absorption is highlighted in the development of photovoltaic applications. This study explores the absorption characteristics of a defective photonic crystal (PhC) in the GHz range. The PhC has the structure (SiO 2 /metamaterial) N /graphene/defect/graphene/(SiO 2 /metamaterial) N . The defect layer is considered as a SiO 2 layer positioned between two graphene sheets. Transmittance, reflection, and absorbance are all investigated. The tunability of absorption characteristics is explored by varying the following parameters: the number of PhC periods, the chemical potential of graphene, the phenomenological scattering rate, and the thickness of the metamaterial layer. The results have shown that the number, frequency position, and intensity of the absorption peaks can be tuned through the change of the optical properties of graphene. The spectra are examined with and without graphene sheets, illustrating that the introduction of two graphene sheets can improve the absorption peaks. This innovative photonic device holds potential in the design of optical components such as filters, absorbers, and sensors in the GHz spectrum, utilizing graphene and metamaterial principles.
