Coupled mode equation effective area
WebUnder the supermode model of coupled MCF, eigenmodes are linear combinations of the core modes [8], so for evaluating average effective area, any normalized mode basis is valid. A convenient basis is the core basis. If overlap between core fields is small, the average effective area of the supermodes is simply MA eff,core, so = (ω 0 n 2 WebApr 11, 2024 · This is because the increase h 3 leads to an increased effective dielectric constant of the resonant mode. The following equation can qualitatively show this relationship [43]: (16) w = ω p / (1 + ɛ e f f) here, ɛ e f f is the effective dielectric constant and the ω p is the plasma frequency of graphene which is related to σ S G (ω, Γ ...
