The optimum design model of two resonators system

In this work we present a new theoretical treatment for the design of two resonator system. Our finding shows our model behaves better than previous models when we consider side-coupling loss for two resonators coupled in a ring configuration. In addition, our model is more physical and intuitive for the analysis of the two resonators system. The properties of the system are studied using the model. The optimum separation between the resonators for the parallel-coupled resonators is provided and the effect of the side-coupling on the system is presented.

► One optimum design model about the two resonators system is presented.
► When we consider side-coupling loss in the system, only our model can work, other models are invalid.
► Our model is more physical and intuitive for the analysis of the two resonators system.
