Abstract
The optical response of Au(110) and Cu(110) surfaces is calculated using the self-consistent method of linear muffin tin orbitals. The imaginary part of the dielectric function determined through electronic interband transitions presents an anisotropy with light polarized along the two directions at right angles from the [110] surfaces. This study establishes that the anisotropy does not result from a geometrical effect but from optical transitions between parallel surface bands.
