State of the Art of Near-Field Scanning: Contemporary Standards and Methods

This paper presents a review of a number of techniques used for near-field scanning and detection of electromagnetic radiation sources. It also gives an overview of standards, related to technical requirements for the devices as well as scanning methods. Subsequently, a comparison between Far Field (FF) and Near Field (NF) is given. We present the advantages of NF over FF, and list the common problems for NF scanning, such as calibration, protraction in overall scanning time. Finally, we refer the possible solutions and improvements for scanning setup and software.
