By using numerical solving of the 1D time dependent Schrödinger equation, we present theoretical study of highorder harmonic generation using plasmonic field enhancement. We show that the strong inhomogeneity feature of field enhancement, plays an important role in HHG process and as a result we obtain a short isolated pulse.
