麦克斯韦方程表明，电介质-金属界面可以支持表面等离子体激元（SPP），这是一种沿着界面与电磁波传播的相干电子振荡波。界面波的独特性质是由金属和介电材料的频率相关色散特性产生的。本章介绍了替代等离子体材料，以及每种材料选择的基本原理。介绍了包括贵金属和半导体在内的各种材料的综合光学特性。光学特性根据 Drude 或 Lorentz 模型定义的介电常数和磁导率进行评估。此外，贵金属是根据固体材料通用手册中普遍认可的数据进行描述的，例如帕利克编辑的固体光学常数手册。本章概述了描述复合纳米结构有效介电功能的有效介质方法。它还为寻找特定频率下更好的等离子体材料提供了参考。
Maxwell’s equations state that a dielectric–metallic interface can support surface plasmon polaritons (SPPs), which are coherent electron oscillation waves that propagate along the interface with an electromagnetic wave. The unique properties of the interface waves result from the frequency-dependent dispersion characteristics of metallic and dielectric materials. This chapter provides an introduction to alternative plasmonic materials, as well as the rationale for each material choice. The comprehensive optical properties of various materials, including noble metals and semiconductors, are presented. The optical properties are evaluated based on the permittivity and permeability defined by either the Drude or Lorentz model. Furthermore, the noble metals are described from the generally approved data in a general handbook of solid materials, such as the Handbook of Optical Constants of Solids, edited by Palik. This chapter outlines the effective medium approaches for describing the effective dielectric functions of composite nanostructures. It also provides a reference for finding better plasmonic materials at specific frequencies.
