Abstract
We present theoretical studies of above-threshold ionization (ATI) produced by nonhomogeneous fields. This kind of fields appears when a plasmonic nanostructure is illuminated by a short laser pulse. Our model is based on the Strong Field Approximation (SFA) and it includes both the direct and the rescattering terms. Electrons with energies far beyond the usual 10Up limit are predicted.
