A network of "phasors"
"Oscillators" in a general sense are dynamical systems, that follow cylclic paths in their phase space. "Phasors" are abstractions of oscillators, where only the location of the system on the cyclic path is considered and not the whole movement in the (possibly higher dimensional) phase space. The location is parameterized as a "phase" in the range [0 : 2 pi]. Networks of such phasors allow to study synchronization properties of more complicated oscillator nets in a simplified way.The simulation shown here consists of a 2 dimensional grid of phasors, where the phases are color-coded. Each phasor interacts with others in a certain range and with a certain strength. Also, each phasor experiences a certain amount of noise. All phasors reveal the same fundamental oscillation frequency.
In dependence of the strength of the interactions and the noise, the phasor network can become engaged into collective oscillations or into a state where each phasor oscillates independent of the others. In between there is a range with more complex collective patterns.
