Theory of the long-periodicity ferrielectric smectic phases [1-3] induced by the electric field is derived. In particular, we obtained the structure of 12-layer phase (qT=2/3) exactly coinciding with the one observed, and we acknowledge the existence of 15-layer phase (qT=11/15) at larger electric field.
