Paper Abstract

We present a theoretical study of the transverse and longitudinal parts of the evanescent electric field from a current density sheet (quantum well). The aim is to identify the part of the evanescent field which upon quantization belongs to the transverse photons. An examination of the field momentum shows that the transverse field is prevented from escaping the evanescent tail by its coupling to the longitudinal field momentum attached to the sheet particles. In the perspective of the four-potential the field-matter interaction is spread over the entire evanescent regime, and in QED this corresponds to an interaction between transverse photons and longitudinal and scalar photons.
