    "abstract": "Surface and curvature properties of asymmetric nuclear matter are studied\nbeyond the proton drip. Using the semiclassical extended Thomas-Fermi method,\nthe calculations are performed in the non-relativistic and relativistic meson\nfield theories (Skyrme forces and non linear sigma-omega parametrizations).\nFirst we discuss the bulk equilibrium between the nuclear and drip phases. Next\nwe analyze the asymmetric surface as a function of the bulk neutron excess. We\nexamine local quantities related to the density profiles and, for two\ndefinitions of the bulk reference energy, the surface and curvature energy\ncoefficients. The calculation of the curvature energy is carefully treated. The\nsensitivity of the nuclear surface to the relativistic effects is investigated.\nMass formulae useful for arbitray neutron excess are discussed, and their limit\nat small asymmetries is compared with the liquid droplet model mass formula.",
