Coherent parametric echoes in nonlinear resonator ensembles

Use is made of the concept of nonuniform (incommensurate) resonator spacings in order to minimize the linear echo problem. The circuit domain simulation of a general class of parametric coherent echoes, previously modeled by means of uniformly spaced nonlinear resonators, is reexamined. This is accomplished by introducing nonuniform (incommensurate) resonator spacings to represent more closely an actual physical system. The effects of this approach in both nonlinearly coupled and anharmonic resonator ensemble models are investigated.<
