Evanescent modes are virtual photons — •Günter Nimtz1 und Alfons Stahlhofen2 — 1Uni Köln, II. Physikal. Inst,, Zülpicher St.r 77, 50937 Köln — 2Uni Koblenz, Physik, Universitätsstr. 1, 56070 Koblenz
Former QED-based studies of evanescent modes indentified these with virtual photons. Recent experimental studies confirmed the resulting predictions about non-locality, non-observability, violation of the Einstein relation and the existence of a commutator of field operators between two space-like separated points. Relativistic causality thus is violated by the near-field phenomenon evanescent modes while primitive causality is untouched.
