Phase fluctuation peak-to-peak magnitude (Δ) distributions in a circular 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. The coupling strength k12 = 40; all other coupling strengths except k1,20 are fixed at 10. k1,20 varies from 30 to 100. (b) Results when f = 0.2 Hz. (c) Results when f = 0.5 Hz. (d) Results when f = 1 Hz.
