The study proposes a broadband absorber for visible band that is designed based on local surface plasmon resonance and incorporating monolayer molybdenum disulfide, gold nanopillars, and Bragg mirrors. Theoretical simulations using the finite-difference time-domain (FDTD) method demonstrated that the MoS₂-based absorber achieved absorptivities exceeding 96.0% and 99.8% at resonance wavelengths of 422 nm and 571 nm, respectively. The spectral characteristics remained stable within an incidence angle range from 0° to 45° and exhibited polarization-independent behavior. Additionally, performance of the absorber could be tuned by modifying the geometric parameters of the periodic gold nanopillar array. This design strategy is applicable to other transition metal dichalcogenides (TMDCs), and its application effectively enhances light-matter interactions in such materials.
