摘要:

纳米结构金属表面上的欺骗表面模式已知具有依赖于周期性图案的几何特征的可定制的色散。在这里,我们研究欺骗等离子体激元色散的隔离光栅和光栅平面镜腔配置。利用散射矩阵方法得到了腔中的欺骗极化激元色散,并引入了相关的微分模态密度,得到了模式色散并对腔极化激元模式进行了分类。光栅镜腔几何形状是平面接地平面上方的周期性纳米结构金属的示例。这里讨论的属性是相关的应用范围从薄的电磁完美吸收近场辐射传热。

英文摘要:

Spoof surface modes on nanostructured metallic surfaces are known to have tailorable dispersion dependent on the geometric characteristics of the periodic pattern. Here we examine the spoof plasmon dispersion on an isolated grating and a grating-planar mirror cavity configuration. The spoof polariton dispersion in the cavity is obtained using the scattering matrix approach, and the related differential modal density of states is introduced to obtain the mode dispersion and classify the cavity polariton modes. The grating-mirror cavity geometry is an example of periodically nanostructured metals above a planar ground plane. The properties discussed here are relevant for applications ranging from thin electromagnetic perfect absorbers to near-field radiative heat transfer.
