Gc. Wetsel et Kj. Strozewski, DYNAMIC-MODEL OF MICROSCALE ELECTROMECHANICAL SPATIAL LIGHT-MODULATOR, Journal of applied physics, 73(11), 1993, pp. 7120-7124
A model based on classical physics describing the nonlinear dynamics o
f a microscale spatial light modulator has been developed. The coupled
electromechanical equations of motion have been solved for steady-sta
te, transient, and harmonic excitation. Comparison of theoretical pred
ictions with the results of experiment for representative devices show
s good agreement for small-amplitude deflections, large-amplitude defl
ections, and unstable transitions.
