如今,石化能源趋于枯竭,癌症严重威胁着人类的生命,开发新能源和治愈癌症成为人类面临的两大迫切需要解决的问题。太阳辐射能取之不尽,用之不竭,是人类理想的新能源,开发太阳能首先需要解决的问题是,提高太阳辐射能收集的效率,而目前的收集效率都不是太理想。治愈癌症的首要问题是要尽早发现癌症细胞,越早诊断出癌细胞,治愈的几率越大。因此,开展以太阳能利用为主要用途的能量收集和以肿瘤细胞高灵敏度探测为主要目的的生物传感器研究具有重要的学术和应用价值。利用有限元法,从理论上研究了不同器件的等离子体纳米结构和吸收体设计。获得了高品质因子和FoM值的多个Fano共振结构。应用对称破缺技术来激发多个高阶暗模。在相对简单的结构中实现了等离子体诱发抗透明（PIAT）和等离子体诱发透明（PIT）。机理上,这种减少对称性是通过引入两个面对面的纳米间隙和在相反方向上旋转/移动这两个纳米间隙来实现的。吸收器设计可用于实现基于高输入电压的可调谐和灵活的完美吸收。基于电光衬底的吸收器非常灵敏,可以用来将谐振波长移动到所需的波段,而不改变光谱的线形。在输入电压变化高度敏感的宽波段,所设计的器件具有与入射角基本无关的吸收特性,可...
