Abstract
In this Letter we analyze a multistrip electrostatic device developing forces of the order of 1 mN on a dielectric mirror. Such a device has been developed for controlling the orientation of suspended mirrors i n long baseline interferometers used for detecting gravitational waves . The dependence of the force on the distance mirror-multistrip has be en measured and the fitting with the computed value has been satisfact ory in the range 0.5-3 mm.
