Angular momentum of non-paraxial light beam: Dependence of orbital angular momentum on polarization
Chun-Fang Li
It is shown that the momentum density of free electromagnetic field splits into two parts. One has no contribution to the net momentum due to the transversality condition. The othe…
Transmission gap, Bragg-like reflection, and Goos-Hänchen shifts near the Dirac point inside a negative-zero-positive index metamaterial slab
Xi Chen, Li-Gang Wang, Chun-Fang Li
Motivated by the realization of the Dirac point (DP) with a double-cone structure for optical field in the negative-zero-positive index metamaterial (NZPIM), the reflection, transm…
Goos-Hänchen shifts in frustrated total internal reflection studied with wave packet propagation
Xi Chen, Chun-Fang Li, Rong-Rong Wei +1
We have investigated that the Goos-Hänchen (GH) shifts in frustrated total internal reflection (FTIR) studied with wave packet propagation. In the first-order approximation of the…
Voltage-tunable lateral shifts of ballistic electrons in semiconductor quantum slabs
Xi Chen, Yue Ban, Chun-Fang Li
It is investigated that the lateral shifts of the ballistic electrons transmitted through a semiconductor quantum slabs can be negative as well as positive, which are analogous to…
Experimental evidence for new symmetry axis of electromagnetic beams
Chun-Fang Li
The new symmetry axis of a well-behaved electromagnetic beam advanced in paper Physical Review A 78, 063831 (2008) is not purely a mathematical concept. The experimental result rep…
Orbital angular momentum is dependent on polarization
Chun-Fang Li
It is shown that the momentum density of free electromagnetic field splits into two parts. One has no contribution to the net momentum due to the transversality condition. The othe…
