Cloaking of Metallic Cube by Plasmonic Shell in Quasistatic Limit

摘要

In this paper cloaking of a cubic metallic object by plasmonic cover is investigated and numerically analyzed. Cloaking of PEC objects by plasmonic covers, especially plasmonic shells, has been recently investigated [1], and promising results have been produced. Most of these work concern with cloaking of sub-wavelength PEC spheres. Cloaking using plasmonic material was first theoretically investigated in reference [2] and [3]. Cloaking of electrically large objects has also been reported [4].
