Abstract
A mesh that separates two regions of different electrostatic field str ength exerts a ''micro-lensing'' effect on charged particles that are transmitted through the mesh, causing the directions of the particles to change. A computational study has been carried out to establish mag nitudes of the directional changes for four types of mesh that are com monly used, square holes in thin and thick plates, welded and woven.
