Within the framework of the mathematical model of the gradient-elastic continuum, i.e. medium, the stress-strain state of which is described by the strain tensor, the second displacement vector gradients, the asymmetric stress tensor and the moment stress tensor, the problem of generating disturbances by a moving source is considered. It is assumed that the source moves at a constant speed along the boundary of half-space. The problem is considered in a two-dimensional formulation, when all processes are homogeneous along the horizontal transverse coordinate axis.
