Microwave cloaking application

Web25 apr. 2013 · The cloaking effect of the realized cloak is characterized by measuring the bistatic scattering patterns of uncloaked and cloaked objects in free space and then comparing these with each other. Recently a new approach to electromagnetic cloaking of long, cylindrical, conducting objects in free space was proposed. 1–3 1. Webmicrowave and optical frequencies [2–9]. In particular, the inherent negative polarizability and fast-wave propagation in ENZ metamaterials allow the envisioning of potential applications in transparency and cloaking devices [2–4] and pattern reshaping [5–7]. As another exciting application for ENZ materials, the
