Spectral power ratio for separation distances of Δz = 40 (top), 80 (middle) and 160 Mm (bottom) for ρ0/ρe = 10 and ϵ = 0.1. The dashed and solid curves represent analytical expressions for the exponential and Gaussian spatial damping profiles, respectively. The exponential damping ratio is recovered by only considering points at a sufficiently large height z>h.
