Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems ...
Abstract: A novel two-dimensional direction finding method is proposed and verified using a 4-element time modulated circular array (TMCA). The received signals from four antenna elements are ...
Abstract: This study presents a comprehensive mathematical model for analyzing optimum frequency hop (FH) patterns (OFHPs) derived from two-dimensional circular shifts applied to a Golomb Costas array ...
