TL;DR: In this paper, a systematic search of literature published during the last fifteen years was carried out and based on the analysis on these papers, these advanced design techniques and methods were summed up as three issues: the kinetic properties of the screen body by dynamic modeling, the optimal screening operational parameters by discrete element method and the dynamic design of the body by finite element method.

Stabilization of electrostatically actuated microstructures using parametric excitation
TL;DR: In this article, the authors demonstrate that the parametric excitation of a microstructure by periodic (ac) voltages may have a stabilizing effect and permits an increase of the steady component of the actuation voltage beyond the pull-in value.
