Singular Electromagnetics: A Symmetry Point of View KU Leuven
Singular electromagnetics, in the visible spectrum also known as singular optics, studies a set of solutions to Maxwell’s equations exhibiting nontrivial topological features. Topological features of an electromagnetic (EM) field refer to the invariant properties of the field configuration under any continuous deformation, which are also termed as topological defects of the EM field. They distinguish one EM field configuration from another, ...
