| Abstract: | The dynamic evolution of Lissajous singularities in free-space propagation is studied. It is shown that the pair creation and annihilation, handedness reversal and change in the degree of polarization of Lissajous singularities, as well as the rotation and change in the shape of Lissajous figures may appear upon propagation. |
