Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of space. These waves have different wavelengths (the distance from wave crest to wave crest) and frequencies, These two are inversely related to each other, the shorter the wavelength, …

Spatial Light Modulator (SLM) for beam steering, optical communications, advanced microscopy and biomedical imaging
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 …

Distributed Coherent RF Arrays of radar, communications and Electronic warfare enable Network-Centric (NCW)
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 …

Terahertz Antennas
Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region. It is within the frequency range of 0.1–10 THz, corresponding to wavelengths of radiation from 3000 to 30 µm. The advantages of the terahertz light are that they are non-invasive, intrinsically safe, and non-ionizing, …
