Abstract
Using the bonding and antibonding orbitals for the valence and conduction bands in germanium and diamond, the nonresonant part of the microscopic dielectric matrix, the local dielectric function, and the microscopic fields induced by a transverse optical field are calculated self-consistently. It is found that the secondary fields are appreciable in both germanium and diamond.
