Formation and destruction of waves with singularities on the spherical wavefront
Formation and destruction of waves produced by a source distributed on a specific circle are considered. The circle belongs to the spherical surface, expanding with the velocity of wave perturbation. The wavefunction expansion is constructed in terms of modes in the cylindrical coordinate system. Final results are compared with expressions obtained earlier for the moving circle of a constant radius.
