Description The different mechanisms of resonant transport of phonons between two media in the presence of impurity
intermediate layer are described. Particular attention is focused on the resonance interaction of elastic
waves with a two-dimensional defect on the contact boundary between two solids, on the multichannel interface
phonon scattering and on the experimentally observed nonmonotonic temperature dependence of the reduced
heat flux. In the cases when there is a direct interaction between edge atoms of the matrix as non-nearest
neighbors or when the impurities do not fill completely the 2D interface layer, the additional channel for
the transmission of phonons through the interface opens. This additional transmission channel manifests itself
as a transmission (or reflection or absorption) peak with an asymmetric line shape (the so-called Fano
resonance for phonons due to interference between the two transmission channels). Some applications of the
Fano effect in magnon heat conductivity are also discussed.
