It turns out that two special mutually orthogonal polarizations exist, which are matched with the axis that is perpendicular both to the waveguide axis and crystallographic axis c of the layered superconductor. The wave of one of the polarizations fully reflects from the layered superconductor and does not excite any field in it, while the wave of the other polarization partly reflects and partly transmits through the layered superconductor. It is important that modes of these two polarizations reflect from the sample independently. Thus, it can be convenient to represent any other polarization via this two. In addition the model for studying dynamic behavior of hybrid system, which consists of classical nanomechanical resonator and quantum subsystem, was created. It is shown that observed quantities such as resonance frequency shift of resonator can be correlated with characteristics of quantum subsystem in terms of parametric capacity. The theory can be used for describing realistic systems, i.e. nanomechanical resonator related in capacitive way to the charge Josephoson qubit and quantum dot based on two-dimensional electron gas.
