  author={Ali Dhinojwala and Steve Granick},
Solid planar plates with area up to several square centimeters can be made parallel at controllable separations from ca. 0.1 ~if airborne dust is eliminated ! to .500mm. Apart from dust and surface roughness, which set the lower bound of plate-plate separation, there is no other fundamental constraint on the type of surface ~metallic or dielectric; opaque or translucent ! that can be studied. When conducting plates are employed, it is possible to apply an electric field in the direction normal… CONTINUE READING
