Surface plasmons are coherent delocalized electron oscillations that exist at the interface between a metal and a dielectric, excited by incident light at specific frequencies. They enable the confinement of electromagnetic fields to subwavelength dimensions, making them crucial for applications in nanophotonics and sensing technologies.

Surface Plasmon

Surface plasmons are coherent delocalized electron oscillations that exist at the interface between a metal and a dielectric, which can be excited by light at specific frequencies. They are pivotal in enhancing electromagnetic fields at surfaces, leading to applications in sensing, photonic circuits, and improving the efficiency of photovoltaic devices.

Incident light refers to the light that falls onto a surface or object before any interaction, such as reflection, absorption, or transmission, occurs. Understanding incident light is crucial in fields like optics and photography, where it influences the appearance and behavior of materials and images.
