The superposition of two light beams with different amplitudes carrying only negative orbital angular momentum (OAM) gives rise to a locally positive OAM in the dark regions. This counterintuitive ...
(a) The effect of permittivity and material rotation angle on the reflection coefficient. (b-c) Asymmetric transmission of vortex waves (positive and negative topological charges) with near-zero ...
This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
