Conducting cylinder in an external field
Abstract
Abstract. For an open conducting cylinder in an axial external field, we calculate the resultant potential and field at all points, and also the longitudinal polarizability. The surface charge densities (interior and exterior) are also calculated. The results are exact in principle, but numerical evaluation requires the inversion of a matrix of known elements. Provided the cylinder is not much longer than its width, matrices are sufficient.
