SUPER-MAXWELL ACTIONS WITH MANIFEST DUALITY

Superstring field theory was recently used to derive a four-dimensiona l Maxwell action with manifest duality. This action is related to the McClain-Wu-Yu Hamiltonian and can be locally coupled to electric and m agnetic 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.
