The use of graphene-based conductors (GBC) as a transmission line (TL) is presented as a conventional TL possessing right-handed (RH) nature and its coupling characteristics are investigated. In order to verify and demonstrate the wave propagation of a GBC TL, a 120 mm long 50 Ω TL was fabricated and tested. Performance of the single GBC TL was then(More)
This paper presents the use of novel Magneto-static Responsive Structures (MRSs) as switching elements in microwave filters to achieve frequency reconfigurability. A single MRS consisted of a small piece of substrate with a cavity drilled out of it. The cavity was then filled with microscopic magnetic particles and capped on both ends with copper tape. In(More)
Many studies have been performed on exploring the effects of radio-frequency (RF) energy on biological function in vivo. In particular, gene expression results have been inconclusive due, in part, to a lack of a standardized experimental procedure. This research describes a new far field RF exposure system for unrestrained murine models that reduces(More)
