| Abstract: | It is shown that when a strong ac electric field acts on an electron in a double quantum well, the dipole moment is an almost
periodic function of the dc voltage applied to the structure. An antipolarization effect — the structure is polarized in a
direction opposite to the external field — appears during one half of the period.
