Using the effective mass and rectangular potentials approximations the theory of dynamic conductivity of electrons is developed for the plane multi-layer resonance tunnel structure within the model of the open nanosystem. The oscillator forces of quantum transitions are studied within the model of the closed nanosystem. For the experimentally produced quantum cascade detector it is proved that just the theory of dynamic conductivity in the model of open cascade most adequately describes the process of absorption of a high-frequency electromagnetic field while the electrons are being transported through the resonance tunnel structure.
