SUMMARY:

Maxwell’s equations are typically presented without considering interaction with matter. In this study, we explore how Maxwell’s equations are formulated when the interaction with matter is taken into account, applying them to a specific problem. Additionally, we introduce the concept of metamaterials—artificially constructed materials exhibiting properties uncommon in natural materials. From this concept, we demonstrate the feasibility of sustaining surface plasmon polaritons (SPPs) in a specific configuration, providing a detailed elaboration of this setup. SPPs in metamaterials possess unique characteristics enabling precise control of light at nanoscales. By designing the geometry and properties of metamaterials, it becomes possible to adjust the resonances of SPPs to interact with light at different wavelengths. This paves the way for applications in advanced optical devices, such as ultra-sensitive sensors, light modulation devices, and integrated optical circuits. The study and development of SPPs in metamaterials represent an ever-evolving research area, offering significant opportunities for advancements in the manipulation and control of light at nanoscales, with potential applications across various areas of optical technology.
