Today's spectrum analyzers aren't your father's instruments. Thanks to lots of embedded processing power, digital signal processing (DSP), and new analog front-end circuitry, the latest round of ...
Vortex light carries orbital angular momentum (OAM) characterized by exp(ilθ), where θ is the angular coordinate and l is the topological charge (TC) 1. OAM beams have been widely used in a variety of ...
Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...
