Abstract :
The dynamical properties of coupled oscillator arrays (COAs) have led to their application as phase shifters in phased array antennas. Harmonic balance (HB) analysis, properly conditioned using auxiliary generator probes in order to guarantee convergence to the oscillating state has been used to accurately model free-running and externally injected coupled oscillator arrays.
