Artificial manipulation of light is significant for the material science and technology. In this work, noticeably enhanced light absorption with absorption above 99% has been demonstrated in a deep-subwavelength meta-surface structure. Dipolar plasmon resonance and near-field coupling of the plasmons between the adjacent core–shell metallo-dielectric spheres together with the optical field coupling by the dielectric shells are the main contributions for the multispectral light absorption. The predicted structure can be fabricated in large-area based on the standard colloidal self-assembled method and the metal deposition technique. These optical and structural features hold the proposed platform to be a potential of the application in light modulation and absorption and other optoelectronics. [ABSTRACT FROM AUTHOR]
