Abstract
A simple surface current model is proposed for studying harmonic generation by a short-pulse high-intensity circularly polarized laser irradiating a solid target normally. Exact relativistic electron dynamics is taken into account. It is found that high harmonics peaked at directions normal to that of incidence are efficiently generated.
