Scattering of elastic surface waves on a localized mechanical load of the surface
This paper presents a model of scattering of elastic su.rface waves (ESW) on a single reflective elements of dot structures loading the surface of a hexagonal structure with a sixfold rotation axis, normal to the plane of propagation. Qualitative results obtained with the use of TIERSTEN type boun~ary conditions  and reduced Green's functions presented by MARADUDIN and DOBRZYŃSKI  are given for a rectangular dot. Resultant components of the scattering amplitude were achieved with the utilization of an ap¬proximation of the stationary phase and approximation of far distances.
