Limit Cycle Oscillations in CW Laser-Driven NEMS
Finite element method (FEM) laser drive limit cycle oscillation self-oscillation thermal stress
2015/8/27
Limit cycle, or self-oscillations, can occur in a variety of NEMS devices illuminated within an interference field. As the device moves within the field, the quantity of light absorbed and hence the r...
