WebApr 21, 2015 · From a physical point of view it means a very high electromagnetic density of states (DOS) that appears as a high rate of spontaneous emission [ 11] and enhancement of all processes of light-matter interaction. However, high DOS photons in HMMs are not coupled with photons in vacuum due to the total internal reflection. WebNov 10, 2024 · According to Wikipedia, permittivity is the ability to resist external electric field. This means a substance with high permittivity requires high external electric field to polarize. On the other hand, susceptibility is defined as the ability to polarize. So a substance with higher susceptibility should polarize easily.
