In this paper, we present an analysis for the radiation from a traveling‐wave infinitely‐extent sheet of monochromatic electric current that is placed at the interface between a conventional lossless dielectric and a lossless material possessing negative real permittivity and permeability. The field distributions and the direction of the Poynting vectors in both half spaces are discussed, and some physical remarks are provided. A brief note about launching Zenneck waves by a line current along this interface is also mentioned. © 2002 Wiley Periodicals, Inc.
