Excitation of coupled phononic frequency combs via two-mode parametric three-wave mixing
Adarsh Ganesan, Cuong Do, Ashwin Seshia
This paper builds on the recent demonstration of three-wave mixing based phononic frequency comb. Here, in this process, an intrinsic coupling between the drive and resonant freque…
Towards N-mode parametric electromechanical resonances
Adarsh Ganesan, Cuong Do, Ashwin Seshia
The ubiquity of parametric resonance is continually evident in the repeated experimental observations of this phenomenon in multiple physical systems. The elementary case of 2 mode…
Phononic frequency comb via three-mode parametric three-wave mixing
Adarsh Ganesan, Cuong Do, Ashwin Seshia
This paper is motivated by the recent demonstration of three-wave mixing based phononic frequency comb. While the previous experiments have shown the existence of three-wave mixing…
Frequency transitions in phononic four-wave mixing
Adarsh Ganesan, Cuong Do, Ashwin Seshia
This work builds upon the recent demonstration of a phononic four-wave mixing (FWM) pathway mediated by parametric resonance. In such a process, drive tones f_d1 and f_d2 associate…
Excitation of multiple 2-mode parametric resonances by a single driven mode
Adarsh Ganesan, Cuong Do, Ashwin Seshia
We demonstrate autoparametric excitation of two distinct sub-harmonic mechanical modes by the same driven mechanical mode corresponding to different drive frequencies within its re…
Anomaly in coupled parametric resonance
Adarsh Ganesan, Cuong Do, Ashwin Seshia
We present experimental observations of an anomaly in the coupled response of auto-parametrically excited microelectromechanical beams. When one of the two coupled beams is driven…
Phononic four-wave mixing
Adarsh Ganesan, Cuong Do, Ashwin A. Seshia
We present the first experimental observations of phononic four-wave mixing (FWM) in a piezoelectrically actuated free-free beam microstructure. The FWM response is facilitated by…
Discrete intrinsic localized modes in a microelectromechanical resonator
Adarsh Ganesan, Cuong Do, Ashwin A. Seshia
Intrinsic Localized Modes (ILMs) or Discrete Breathers (DBs) are produced through a non-linear vibration localization phenomenon. While Anderson localization is due to lattice defe…
Phononic High Harmonic Generation
Adarsh Ganesan, Cuong Do, Ashwin A. Seshia
This paper reports experimental evidence for phononic low-order to high-order harmonic conversion leading to high harmonic generation. Phononic high harmonic generation is mediated…
Hyperfine phononic frequency comb
Adarsh Ganesan, Cuong Do, Ashwin A. Seshia
Optical frequency combs [1-8] have resulted in significant advances in optical frequency metrology and found wide application to precise physical measurements [1-4, 9] and molecula…
