Plasmonics

"In physics, the plasmon is the quasiparticle resulting from the quantization of plasma oscillations. They are a hybrid of the electron plasma (in a metal or semiconductor) and the photon. Thus, plasmons are collective oscillations of the free electron gas at optical frequencies.

A plasmon is basically just an oscillation of the conduction electrons in a metal.

This definition suggests that plasmons are strictly quantum mechanical entities, but many of their important properties can be derived directly from Maxwell's Equations.

It is the classical electrodynamical picture that is implied in most of the modern literature on plasmons. And for simulations of plasmons in complex geometry no free electrons are simulated, but simply the dielectric constant for a given frequency is used (or the local impulse response if you use time instead of frequency). No nonlocal interaction (like the one which is needed for high-precision UV lithography lens simulation) is needed."

Thanks SolarEagle I was not sure when I first saw this item as how to take it, I do know a fairish amount about many items of theoretical physics, but this caught me napping. Glad to to you were awake.

hello you seem to have a vast knowledge off physics do you know what device i could take apart to get a source of positrons or photon energy thank you

Me too, is that related to microtech? is it dangerous?
