Scanning the Literature.

The Scanning the Literature column provides concise summaries of selected papers that have recently been published in the field of networking. Each summary describes the paper's main idea, methodology, and technical contributions. The purpose of the column is to bring the state of the art of networking research to readers of IEEE Network. Authors are also welcome to recommend their recently published work to the column, and papers with novel ideas, solid work, and significant contributions to the field are especially appreciated. Authors wishing to have their papers presented in the column should contact the Editor. Metamaterials are artificially engineered materials with electromagnetic (EM) properties that are not owned by natural materials, which could be composed of subwavelength-scale meta-particles arranged periodically or quasi-periodically. How to utilize such materials to enhance capabilities of communication has become an interesting issue attracting attention from both the science and engineering communities. The column in this issue focuses on recent research on electromagnetic metamaterials, in particular, Chiral Metamaterials, leaky-wave antennas, and digital coding and programmable metasurfaces.
