So if we’re right, each former human is now essentially a radio transmitter and receiver. One plurb sends out a signal that ...

Abstract: This paper proposes a novel radar jamming method based on an amplitude-phase hybrid modulation mechanism. Utilizing a dual-drive Mach-Zehnder modulator (DDMZM) for radar signal modulation ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

Welcome to the Department of Physics and Astronomy at the University of Delaware, where the pursuit of scientific discovery and innovation meets cutting-edge research and academic excellence. Our ...

Abstract: In this letter, we propose a multilevel coded modulation (MLCM) scheme based on single parity check (SPC)-aided spatially coupled low-density parity-check (SC-LDPC) codes to enhance spectral ...
