    "abstract": "The notion of ``radiating\u0027\u0027 and ``non-radiating\u0027\u0027 current sources in\nclassical electrodynamics plays an important role in calculations of direct and\ninverse electromagnetic scattering problems. Such a decomposition of the\ncurrent is central for the notion of localized non-radiating electromagnetic\nmodes. A completely quantum electrodynamic view is explored in this work.\nPhoton emission and absorption current sources are classified as being either\nradiating or non-radiating. This quantum classification corresponds,\nrespectively and exactly, to the notion of ``real\u0027\u0027 and ``virtual\u0027\u0027 photon\nprocesses. Causal properties of both real and virtual electromagnetic fields\nare discussed.",
