So I've had some rough descriptions of how plasmon resonance works in the context of surface plasmons because that's applied science. Can anyone explain to me what the predicted behavior of plasmons would be in 1D? Should there be a resistance factor, I mean is resistance even an issue with plasmon propagation?

Must the metal be contiguous like a screen, plate, or strand? Or can the resonance transfer over a small gap? If so to the latter, energy transfer is reduced exponentially with distance, do plasmons behave the same way? Do they lose energy to the environment?

What about the difference between solid-solid, solid-gas, and solid-liquid interfaces? In surface plasmon resonance, the change in damper thickness alters the output. Is that dependent on molecular weight? Electron density? Physical dimensions? Water content?

Thank you
