We study the effect of unidirectional reflection in the bilayer optical model with the balanced loss and gain terms. It was found that if the impedances characterizing the scattering part are different from those describing the leads, an effect of switching of unidirectional reflection emerges. In this case the vanishing reflection occurs both for the left and for the right incident wave, depending on the wave frequency. It is shown that the alternation of the unidirectional reflection from the left to the right can occur even if the corresponding Hamiltonian is non-PT-symmetric. Our analytical results are demonstrated by numerical data.
