A modeling and design approach is proposed for nanoparticle-based electromagnetic devices. First, the structure properties were analytically studied using Maxwell's equations. The method provides us a robust link between nanoparticles electromagnetic response (amplitude and phase) and their geometrical characteristics (shape, geometry, and dimensions). Secondly, new designs based on "metamaterial" concept are proposed, demonstrating great performances in terms of wide-angle range functionality and multi/wide behavior, compared to conventional devices working at the same frequencies. The approach offers potential applications to build-up new advanced platforms for sensing and medical diagnostics. Therefore, in the final part of the article, some practical examples are reported such as cancer detection, water content measurements, chemical analysis, glucose concentration measurements and blood diseases monitoring.
提出了一种基于纳米粒子的电磁器件的建模与设计方法。首先，利用麦克斯韦方程组对结构特性进行了分析研究。该方法为我们提供了纳米粒子电磁响应（幅度和相位）与其几何特征（形状、几何结构和尺寸）之间的有力联系。其次，提出了基于“超材料”概念的新设计，与在相同频率下工作的传统器件相比，在广角范围功能和多/宽行为方面表现出优异的性能。该方法为构建新型先进的传感和医学诊断平台提供了潜在应用。因此，在文章的最后部分，报告了一些实际例子，如癌症检测、水分含量测量、化学分析、葡萄糖浓度测量和血液疾病监测。
