- We consider the behavior of level lines of two-dimensional potentials, which play an important role in the physics of ``two-layer'' systems. Potentials of this type are quasiperiodic and, at the same time, can also be considered as a model of random potentials on a plane. The description of level lines of such potentials is a special case of the Novikov problem for potentials with four quasiperiods and uses many features that arise in the study of the general Novikov problem. At the same time, the potentials under consideration also have their own clearly expressed specificity, which makes them very interesting for research from a variety of points of view.
