WebApr 4, 2024 · Electrostatic curtains can be simple and yet efficient devices to manipulate micronized particles on flat surfaces. This paper aims to investigate the motion of a 60 µm dielectric particle on the surface of a standing-wave conveyor. The study is based on a numerical model that accounts for the many forces that could potentially influence … WebThe textbook also introduce the divergence of dielectric displacement is free charge density. However it doesn't think about surface bound charge. ϵ 0 ∇ ⋅ E = ρ = ρ free + ρ bound. I think we should add surface bound charge σ b in the above equation. The Griffiths wrote why he did not add it but I don't understand the logic of Griffiths.
