From: Low-frequency oscillations in coupled phase oscillators with inertia
Phase fluctuation in a linear 20-node network driven by an external periodic forcing A sin (2πft). The damping coefficient α = 0.2 and forcing amplitude A = 1. (a) The network topology. The numbers in the circles indicate the power at the respective nodes. The forcing is added to the generator (red) node 1 at t = 30 s and removed at t = 250 s. (b) Propagation of phase oscillations along the chain with f = 0.2Hz and various global coupling strength k. The propagation is represented by the time the oscillation starts at each node. (c) Propagation of phase oscillations along the chain with k = 60and different driving forcing frequencies f. (d) Propagation of phase oscillations along the chain with k = 60, f = 0.2Hz, and different damping coefficients α.
