Abstract: | Considering the Love problem as an example, we derive relations connecting the following two exact integral representations of its solution: one explicitly involving both damped and undamped modes (residues at the roots of the dispersion equation of the problem) and the other based on expanding the interference field into a series of a geometric progression. In the latter case, to each such summand a generalized ray of a wave of certain multiplicity propagating in the layer can be put into correspondence. By using the methods of contour integrals, a correspondence between the set of multiple waves and interference modes is established. Bibliography: 1 title.
