Media is any form of research output that is recorded and played. This is most commonly video, but can be audio or 3D representations.
Off-axis diffraction of a vortex beam with w= 0.3 mm and l=+3 from a sinusoidal ZP with f=40 cm and offset x_0=3 mm, under propagation from z=0 to z=f. First row shows the intensity and the second row shows the corresponding phase profiles.
