论文摘要
在这项工作中,我们提出了由金属和介电双层形成的epsilon-near-near-near-near-near-near-near-near-near-near-near-nar-hoparticles,并采用了有效的培养基方法来研究其光学响应。我们通过改变了所提出的双层纳米球的半径,从而获得了一个被动调节的ENZ区域,从可见到近IR。此外,我们使用开源的基于转移的基质软件(Strateify)介绍ENZ纳米颗粒的吸收和散射横截面。 %,以及商业FDTD软件(Lumerical)。提出的ENZ纳米颗粒被设想为使用化学合成技术实验实现。
In this work, we propose epsilon-near-zero (ENZ) nanoparticles formed of metal and dielectric bilayers and employ the effective medium approach for multilayered nanospheres to study their optical response. We obtained a passive tunable ENZ region by varying the radii of the proposed bilayer nanospheres, ranging from visible to near-IR. In addition, we present the absorption and scattering cross-section of ENZ nanoparticles using an open-source, transfer-matrix-based software (STRATIFY). %, and a commercial FDTD software (LUMERICAL). The proposed ENZ nanoparticle is envisioned to be experimentally realized using chemical synthesis techniques.
