Infrared radiation detectors are a critical component for DoD imaging systems used in areas such as military vehicles, military night vision, military communication, environmental monitoring, and target acquisition. In addition, they are crucial for commercial markets including surveillance, digital cameras, automotive and scientific research. Common constraints for IR sensors …

The general-purpose computer has remained the dominant computing architecture for the last 50 years, driven largely by the relentless pace of Moore’s Law. As this trajectory shows signs of slowing, however, it has become increasingly more challenging to achieve performance gains from generalized hardware, setting the stage for a resurgence …

Due to the growing, insatiable thirst for information, both commercial and defense communications are driving towards increasingly higher data rates and wider bandwidths of operation. This in turn is driving systems toward higher operating frequencies, which more easily supports larger channel bandwidths. For example, today’s cellular networks (i.e., cellular networks …

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 (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, …

As a vessel travels under or on the surface of water, it causes a detectable local disturbance in Earth’s magnetic field. This disturbance, referred to as the magnetic signature, makes the vessel vulnerable to enemy defense systems. In submarine warfare, adversaries use increasingly sophisticated magnetic sensor and signal processing equipment to …

The control of electric currents in solids is at the origin of modern electronics which has revolutionised our daily life. The diode and the transistor introduced by Braun and Bardeen and Brattain are undoubtedly the corner stones of modern information technologies. Such devices allow for rectifying, switching, modulating, and even …

An electronic connector is an electro-mechanical device whose purpose is to quickly and easily disconnect or interrupt a circuit path or electrical circuits . Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. The connection may be removable …
