The enhancement is related to the electromagnetic coupling of the localized surface plasmon resonance of silver metal particles and the surfacepolariton of the silver substrate.
These effects are explained by the surface plasmon polariton Bloch modes and self-focusing theory.
这些效应可以用表面等离子体激发和自聚焦理论来解释。

In the study of MIM tunnel light-emission junctions, whether SPP (surface plasmon polariton) "fast" mode or SPP "slow" mode holds more important role is always a main topic.
