Abstract

The design of plasmonic metasurfaces is often based on solving the Maxwell electromagnetic equations, which can be a time-consuming and expensive process considering many geometrical parameters that can limit design flexibility. To speed up the design flow, a model based on the classical transmission line theory is presented. The proposed equivalent circuit model can predict the plasmon resonance wavelength based on various geometrical parameters including dielectric thickness and disk diameter. In addition, unlike other reported circuit models, the developed model considers the nanostructure array pitch size, which is crucial in metasurface design. Comparison between the results obtained from circuit model and full wavelength simulation showed that the circuit parameters accurately determine the response of the structure. Finally, as a metasurface design demonstration, we utilized our model to simulate aluminum-based gap-plasmon nanodisk arrays for optimizing their optical response to maximize structural color saturation.

间隙-等离子体纳米盘谐振器电路模型的应用
质子元表面的设计通常基于麦克斯韦电磁方程的求解,考虑到可能限制设计灵活性的许多几何参数,这一过程可能既耗时又昂贵。为了加快设计流程,本文提出了一个基于经典传输线理论的模型。所提出的等效电路模型可以根据各种几何参数(包括介质厚度和圆盘直径)预测等离子体共振波长。此外,与其他已报道的电路模型不同,所开发的模型考虑了纳米结构阵列间距尺寸,这在元表面设计中至关重要。电路模型和全波长仿真结果的比较表明,电路参数准确地决定了结构的响应。最后,作为元表面设计演示,我们利用我们的模型模拟了铝基间隙-等离子纳米盘阵列,以优化其光学响应,最大限度地提高结构色彩饱和度。

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
