Abstract

The field of an SV-source of transverse waves in a solid homogeneous layer with free boundaries is found. In addition to transverse waves, longitudinal waves arise at these boundaries. The total field in the layer is characterized by scalar and vector potentials. Due to the axial symmetry of this field, the vector potential has only an angular component. The integral representation of the potentials was obtained by the Fourier–Bessel method. Based on residue theory, the field in the layer is represented as the superposition of cylindrical Lamb modes. The amplitudes of these modes are calculated.
