Evolution of tunable phononic frequency combs via three-mode interaction in curved piezoelectric micromachined ultrasonic transducers

Abstract Phononic frequency combs are the mechanical counterparts of optical frequency combs, representing a pivotal progression in nonlinear studies of micro-electromechanical systems. This work presents the generation of tunable frequency combs based on three-mode interaction through combination i...
