Abstract

This paper addresses a deficiency in the authors´ previous work on coupled-oscillator theory, involving the nature of the resonance in the oscillator equivalent circuit and its influence on the stable modes of the, coupled-oscillator system. The authors show that series and parallel oscillators with identical free-running characteristics nevertheless behave differently when coupled by the same coupling network. The analysis focuses on parallel-coupling networks, which are most practical at microwave frequencies, and specifically on nearest-neighbor coupling topologies. The theory is verified using four small active-patch arrays operating at 10 GHz
