Semiconductor lighting technology is developing rapidly. While seeking high luminous efficiency, low cost, and superior reliability, researchers are increasingly focusing on the effects of LED ...
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 ...
