The time- and space-dependent non-linear current response to a monochromatic ac-electric field at a tunnel barrier in a one-dimensional interacting electron system is investigated within the Luttinger liquid model. The current harmonics are studied and the corresponding emitted electromagnetic powers are calculated.
