“…For example, they are present in the plots for an elastic layer bounded to a rigid base [6]. However in that case, the localization of every mode periodically repeats in frequency, unlike to the localization of every mode in only one band observed in Figs.…”

The paper is focused on the source energy distribution in vertically inhomogeneous elastic halfspaces with soft internal channels. The analysis is performed using the Fourier transform technique and Green's matrix integral representations. Timeaveraged wave energy fluxes are calculated based on the Umov-Poynting energy vector concept. The excited guided waves exhibit a peculiar effect of wave energy localization in certain, specific for each wave mode, frequency ranges. Outwardly, it looks like a successive energy forwarding from every current mode to the next one.

The paper deals with guided waves generated by a surface load in a coated elastic half-space. The analysis is based on the explicit integral and asymptotic expressions derived in terms of Green's matrix and given loads for both laminate and functionally graded substrates. To perform the energy analysis, explicit expressions for the time-averaged amount of energy transferred in the time-harmonic wave field by every excited guided or body wave through horizontal planes and lateral cylindrical surfaces have been also derived. The study is focused on the peculiarities of wave energy transmission in substrates with soft interlayers that serve as internal channels for the excited guided waves. The notable features of the source energy partitioning in such media are the domination of a single emerging mode in each consecutive frequency subrange and the appearance of reverse energy fluxes at certain frequencies. These effects as well as modal and spatial distribution of the wave energy coming from the source into the substructure are numerically analyzed and discussed.
