Lots of key words in this paper grabbed my attention.And if you really want to do a deep dive, it was an Airforce Research Project from Wright Patterson AFB: F33615-98-D-3210(snip)"The spatial and temporal profiles of electron density, ion density, and voltage have been obtained. The electrons and ions move in response to applied rf voltage, with the response of ions being delayed as compared to that of electrons. This results in charge separation and generation of an electrostatic field. The force is positive over the domain during the positive part of the cycle because of the obvious reason that the electric field is towards the positive direction. During the negative part of the cycle, electrons get deposited over the dielectric surface surrounding the grounded electrode, and the dielectric surface starts working as a virtual negative electrode and the effect of grounded electrode gets cut off. The force is negative only when the voltage changes sign because there is not sufficient deposition of the electrons over the dielectric surface. The time average value of force per unit area in an x direction is positive and in a y direction is negative, which implies that there is an average net electric body force on the plasma in the positive x and negative y directions. This will result in a moving wave of plasma over the dielectric surface in the direction of positive x attenuating faster outside the electrode arrangement. This will be significant for flow control and other relevant applications."© 2005 American Institute of Physics.
