In this paper, an ultra-wideband (UWB) antenna array for through-wall microwave imaging (TWMI) system is introduced. The detection system consists of 4-element balanced antipodal Vivaldi antenna array (BAVA) fed by 1-to-4 UWB modified Wilkinson power divider. The antenna element, array, and feed network are optimized, fabricated and tested. The main working(More)
The radiation-induced bystander effect, wherein unirradiated cells near to or sharing medium with irradiated cells express biological responses, most often has been studied in two-dimensional monolayer cultures, although some studies with three-dimensional models and in vivo have also shown bystander signaling. We have shown previously that DNA damage,(More)
