The microparticles interaction with potential barriers of various nature and form is the quantum physics and nanoelectronics basis. The nature of this interaction largely determines modern radio engineering devices and complexes operation, information transmission and processing systems. At present, semiconductor quantum-well structures, in particular heterostructures with quantum wells (QWs) and barriers (QWs), occupy leading positions as materials for opto- and nanoelectronics. It has been found that chain consisting of a sequence formation of potential wells and barriers gives rise to resonant levels for which the structure transparency is equal to unity. With an increase in the number of chain links, these levels split into close sublevels, the energy and half-width of which depend on the barriers parameters and the number of chain cells. A technique is proposed to determine the characteristics of these levels, in particular, the half-width of sublevels. The wave function dependence on chain parameters is studied. Problems related to the propagation of waves in layered media also arise in many other branches of science and technology. In particular, such media as plasma, ionosphere, atmosphere, ocean contain layered structures. Solving the problems of wave propagation in these media, calculating the reflection and transmission coefficients during the propagation of electromagnetic waves are of great importance both for calculating radio paths with reflection from the ionosphere and for many problems of remote diagnostics of ionospheric plasma. The issues discussed in this paper may be of interest to specialists in these areas.
