Time autocorrelation functions of the coefficients in the Fourier series fit to the membrane's height, h(x,y,t). The composition of each point in the EM network is set to φ = φ_c = 0.6. Here k_max ≈ 4.44 × 10⁶ cm⁻¹ and Δk = k_max/10. The correlation function labeled k_* corresponds to a Fourier mode with a wavenumber ∼6.3 × 10⁶ cm⁻¹. As the wavenumbers increase above k_max, the undulating modes go from being damped to overdamped. Persistent oscillations (not shown) occur for p ≤ 5. These oscillations are particularly apparent if a single (no averaging over modes) Fourier mode is inspected.
