Cassie-wenzel wetting transition in vibrating drops deposited on rough surfaces: Is the dynamic cassie-wenzel wetting transition a 2D or 1D affair?

The transition between the Cassie and Wenzel wetting regimes has been observed under vertical vibration of a water drop placed on a rough micrometrically scaled polymer pattern. The transition takes place under the constant force per unit length of the triple contact line, not under constant pressure. A study of the vibrating drop deposited on the rough surface supplied valuable information concerning the Cassie-Wenzel wetting transition.
