The behavior of dielectric droplets deposited on a superhydrophobic surface and exposed to a constant and uniform electric field is investigated. The change in the droplet shape is described by a linear dependence of its eccentricity on the applied electric field. The proposed control of the droplet shape with the electric field may serve as an alternative to electrowetting technologies.

    A technique to control the trajectory of in-flight microdroplets is described. The localized electric field generated by a needle electrode applies the dielectrophoretic force to the droplet to deflect its trajectory. Deflection by as much as 0.2 rad can be achieved, sufficient for industrial...

    The static value of the effective dielectric constant in a thin film capacitor is simulated by means of the local field theory. The value of it shows a sharp decrease as the film thickness is decreased in an ultrathin film geometry. This phenomenon is due to the size effect intrinsic to a thin...
