What is Surface Plasmon Resonance?

[PhysicsEnjoyer31415]

TL;DR

Can someone please explain to me SPR in detail and mathrmatics of it if any. I have a basic idea that it is something like photoelectric effect but instead of electron a photonof different wavelength is shot off because some of the energy is absorbed by the material. Am i correct ? Please help .Thank you.
