The field value is non-uniform and high at the corners and depends on different parameters, such as the radius of the corner, the radius and height of the protrusion or the depth of the indentation and there is also a direct influence from these parameters on the Faraday cage effect.

Injecting particles of size 35 渭m diameter achieves a good compromise between reducing the effect of streamlines of air flow and minimizing the Faraday cage penetration problem as well as the edge effect.

There is very good correlation between the calculated electric field and the predicted values of the deposition thickness on targets with surface perturbation.
