Null-Field Radiationless Sources: Comment
arXiv:1509.03506 · doi:10.1364/OL.40.002365
Abstract
We elaborate upon a recent paper of E. Hurwitz and G. Gbur [Opt. Lett. {\bf 39}, 6529 (2014)], dealing with null-field sources. After commenting on their theory in Minkowski space, we show how the theory can be conveniently generalized to the case of curvilinear space.
