| dc.description.abstract | A single electromagnetic plane-wave propagating in free space possesses neither spin nor orbital angular momentum. Both types of angular momentum arise from interference between pairs of plane-waves having the same temporal frequency ω but differing k-vectors k1 and k2. While it is fairly straightforward to evaluate a wavepacket’s spin and orbital angular momenta in the (k, ω) continuum by means of Fourier transformation, obtaining the same results by discretizing the (k, ω) space, then attempting to approach the continuum limit via an infinite enlargement of the spatial volume under consideration, is fraught with danger. © 2023 SPIE. | |
