what is "plasmonic resonance"
hi, could somebody who is familiy with "plasmonic resonance" tell me about it?
thank you!

Plasmonic resonance is a phenomenon that occurs when a material's free electrons oscillate in response to an external electromagnetic field, leading to enhanced light-matter interactions.
Plasmonic resonance works by using the collective oscillation of free electrons in a material to amplify and manipulate light at the nanoscale. This creates a strong coupling between light and matter, allowing for enhanced light absorption, scattering, and emission.
Plasmonic resonance has a wide range of applications in various fields, including bioimaging, biosensing, solar energy harvesting, and data storage. It is also being explored for use in nanophotonic devices and as a tool for manipulating light at the nanoscale.
Materials that exhibit plasmonic resonance typically have a high concentration of free electrons, such as metals like gold, silver, and copper. However, other materials, such as semiconductors and graphene, can also exhibit plasmonic behavior under certain conditions.
Localized plasmonic resonance occurs when the collective oscillation of electrons is confined to a small region, while propagating plasmonic resonance involves the propagation of electromagnetic waves along the surface of a material. Localized plasmonic resonance is typically used for sensing and imaging applications, while propagating plasmonic resonance is used for waveguiding and light manipulation.
