Abstract
This study proposes a polarization-independent narrowband absorber based on silicon dioxide and gold composition, which can work for both TE and TM polarizations. The transverse electric polarization absorption efficiency of the absorber at 731 nm is 99.34%, and the transverse magnetic polarization absorption efficiency at 741 nm is 94.82%. We studied the normalized electromagnetic field distribution at resonance wavelengths under TE polarization and TM polarization, which could illustrate the electromagnetic intensity distribution in the absorber. Finally, the parameter tolerance of the absorber was studied and analyzed, and it was found that this polarization-independent narrowband absorber has great application prospects. It can be applied in fields such as high-sensitivity sensors and optical detection.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
