Abstract
A non-intrusive approach for personal surveillance is explored. A potential strategy for identification of electronic devices using electromagnetic illumination with the aim of identifying unique resonances and signatures is presented. The concept is that signatures can be compared to a known signature for a particular device. If discrepancies are detected, then the device may be flagged as a suspect item. Various antenna structures are analyzed to determine the ideal antenna characteristics needed for electromagnetic illumination. A double ridged horn antenna is designed, characterized and compared to a conical spiral right hand circular polarized antenna and a standard gain antenna. Various passive structures and electronic devices are illuminated with electromagnetic energy and responses analyzed.
