Abstract

When two eigenmodes are at internal resonance (IR), i.e. they have commensurate eigenfrequencies, their coupling strength can be significantly enhanced. Rich nonlinear dynamics have been shown at IR. In this work, we present a novel non-monotonic energy dissipation rate of microelectromechanical systems (MEMs) at IR. We demonstrate that the MEMs can selectively dissipate via two largely distinctive pathways, solely depending on the choice of their relative initial phase. Remarkably, these novel and complicated behaviors can be modeled by an intuitive parametric-oscillator-like model. Our work illuminates a path to dissipation engineering, frequency stabilization, and sensitivity enhancement.
