Completion of plane-symmetric metrics yielded by electromagnetic fields

Abstract

It is proven that the plane-symmetric metrics associated with the plane-symmetric nonnull electromagnetic fields given by Letelier and Tabensky [2], together with the plane-symmetric metrics associated with the semi-plane-symmetric null electromagnetic fields, given by Li and Liang [3], exhaust the planesymmetric metrics yielded by electromagnetic fields. A “dual interpretation” to the latter metrics, explaining them as being associated with null electromagnetic fields with source, is also given.
