A spatial light modulator (SLM) is a special device that can manipulate light by modulating the amplitude, phase or polarization of the light waves in the two dimensions of space and time. This means that light is manipulated in order to obtain a desired output, and SLM is commonly used …

Researchers are exploring the possibilities of combining the operations of distributed mobile systems with coherence at the radio frequency (RF) level, called coherent RF arrays, and the microwave and millimeter-wave technologies necessary to get there. The term “distributed” makes explicit that either the transmission or the reception function is divided …
