his work investigates the properties of an antenna-like configuration with an electric line source radiating in the presence of a double-negative circular cylinder. First, the analytical eigenfunction-series solution is derived. Second, this solution is employed in numerical calculations to study the properties of the near field, inside as well as outside the cylinder, and the far-field. Third, the variations of these fields are examined, as well as the radiation resistance and radiation pattern, as functions of the geometrical and electromagnetic parameters of the configuration. It is demonstrated that the scattering properties of the double-negative cylinder are vastly different from those of the corresponding double-positive cylinder. In particular, the focusing effect inside the cylinder and the angular variation of the directivity exhibit distinct characteristics
