Plasmonics is a rapidly growing field of research that focuses on the interaction between electromagnetic fields and free electrons in metal nanostructures. These interactions lead to the generation of surface plasmons, collective electron oscillations that can significantly enhance the local electromagnetic field and light-matter interactions. Plasmonic effects can be exploited for various applications, such as sensing, imaging, data storage, energy harvesting, and photonic devices. Researchers in this field are exploring the fundamental properties of plasmonic materials, designing novel nanostructures, and developing new technologies based on plasmonics.
