Abstract

Localized surface plasmons (LSPs) in metal particles are used in medical, chemical, physical, and biological sensing applications. In this paper, we revisit the classical description of LSPs. We use the Drude model and the Quasi-Static approximation to describe the plasmon resonances in terms of the material and the size of the particles embedded in a dielectric host. We then incorporate the Clausius–Mossotti relation to include shape effects in the classical description. Finally, we incorporate surface damping and retardation effects to arrive at a unified, classical description providing an intuitive and realistic model of plasmonic resonances in metal particles.

金属纳米粒子等离子体共振的解析计算:简单指南

金属粒子中的局部表面等离子体(LSPs)用于医学、化学、物理和生物传感应用。在本文中，我们回顾了lsp的经典描述。我们使用Drude模型和准静态近似来描述等离子体共振的材料和粒子嵌入在介电介质主机的大小。然后，我们结合克劳修斯-莫索蒂关系，在经典描述中包括形状效应。最后，我们将表面阻尼和延迟效应结合起来，得到了一个统一的经典描述，提供了一个直观和现实的金属粒子等离子体共振模型。

期刊介绍： The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
