研究目的
Investigating the excitation of anapole modes in dielectric nanodisks with lower refractive indices supported by metallic or near-zero-index substrates and demonstrating highly efficient coherent generation of vacuum ultraviolet via second-harmonic generation.
研究成果
The index contrast between the substrate and dielectric nanoparticle is crucial for exciting anapole modes with highly enhanced near-field, enabling highly efficient coherent generation of vacuum ultraviolet via second-harmonic generation. This approach offers potential applications in VUV spectroscopy and sensing at the nanoscale.
研究不足
The study is based on numerical simulations and lacks experimental validation. The practical implementation may face challenges in fabricating nanodisks with precise dimensions and material properties.
