DOI: 10.1103/physrevb.98.165419
Abstract: Quality of spatial separation between electric and magnetic fields in an electromagnetic wave is fundamentally constrained by nonlocal nature of Maxwell equations. While electric and magnetic energy densities in a wave, propagating in vacuum, are… read more here.
