INFLUENCE OF THE OSCILLATOR EQUIVALENT-CIRCUIT ON THE STABLE MODES OFPARALLEL-COUPLED OSCILLATORS

This paper addresses a deficiency in the authors' previous work on cou pled-oscillator theory, involving the nature of the resonance in the o scillator equivalent circuit and its influence on the stable modes of the coupled-oscillator system, The authors show that series and parall el oscillators with identical free-running characteristics nevertheles s behave differently when coupled by the same coupling network, The an alysis focuses on parallel-coupling networks, which are most practical at microwave frequencies, and specifically on nearest-neighbor coupli ng topologies, The theory is verified using four small active-patch ar rays operating at 10 GHz.
