Natural photonic crystals (PCs) such as those in butterfly wings have been vastly utilized in signal enhancement applications. In recent years, simulations are mostly related to the color generation phenomenon and reflection properties of butterfly wings, and few of them focus on the localized electric field. Herein, a general exploration of electromagnetic modeling of bioinspired PC-incorporated gold nanoparticles (AuNPs) for enhancing the localized electric field has been illustrated. With the aid of PC, the incorporated system can produce stronger electric fields than AuNP(s). The highest increment of |E|_max is 1.96 times from AuNP alone for the AuNP-PC system and 1.86 times for the dimer-PC system.

掺入光子晶体的金纳米粒子的FDTD建模以增强局部电场

诸如蝴蝶翅膀中的天然光子晶体（PC）已被广泛用于信号增强应用中。近年来，模拟大多与蝴蝶翅膀的发色现象和反射特性有关，而很少有人关注局部电场。本文中，已阐明了对生物启发的掺有PC的金纳米颗粒（AuNP）进行电磁建模以增强局部电场的一般探索。借助PC，内置系统可以产生比AuNP强的电场。|的最高增量 E | 对于AuNP-PC系统，_最大值是单独AuNP的1.96倍，对于二聚体PC系统，_最大值是1.86倍。
