Super-Maxwell Actions with Manifest Duality
  Superstring field theory was recently used to derive a four-dimensional Maxwell action with manifest duality. This action is related to the McClain-Wu-Yu Hamiltonian and can be locally coupled to electric and magnetic sources.   In this letter, the manifestly dual Maxwell action is supersymmetrized using N=1 and N=2 superspace. The N=2 version may be useful for studying Seiberg-Witten duality.
