In quantum mechanics, spin is an intrinsic form of angular momentum carried by elementary particles. Spintronics is “A branch of physics concerned with the storage and transfer of information by means of electron spins in addition to electron charge as in conventional electronics.” Spin-based electronics focuses on devices whose functionality …

Nanomaterials are often categorized based on number of dimensions of a material, which are outside the nanoscale (<100 nm) range. Accordingly, in one-dimensional nanomaterials (1D), one dimension is outside the nanoscale. This class includes nanofibers, nanotubes, nanorods, and nanowires. 1D materials are generally considered to be high‐capacity and stable electrode materials, due …

In April 2001, a US Navy surveillance plane was intercepted by two Chinese F-8 fighter planes during a routine patrol flight over the Chinese South Sea. The US plane was forced to make an emergency landing in China, after what officials described as a “minor” midair collision, occurred with one of the Chinese planes. The US …

Sonars are one of the primary systems for detection and tracking of submarines in Anti Submarine warfare. However modern nuclear and diesel electric submarines have become very stealthy and quiet. Another challenge is diesel-electric submarines operating in littoral waters which generate high false alarm rates (FAR). One of the ways …

The GPS system provides critical positioning capabilities to military, civil, and commercial users around the world. However, in many environments in which military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access. It can be significantly degraded or unavailable during solar …

U.S. military researchers are asking for industry’s help in developing a combination hybrid analog, digital, photonic, and electronic processor to help analyze RF and optical signals for situational awareness. The project seeks to enable U.S. and allied warfighters to understand in near-real-time all the waveform details, source type and class, …

Radio frequency waves (RF) are electromagnetic waves between the frequencies of 3 kilohertz to 300 gigahertz, used in radio, cellphones, wi-fi, radar, GPS, and many other systems. While humans have used RF technology to communicate for over 100 years, no living organism has ever been observed using RF to communicate …

Recent military conflicts have demonstrated the need for close air support from precision attack platforms (e.g., the AC-130 gunship) to support ground forces. These aircraft typically use IR sensors to engage moving ground targets, such as vehicles and dismounts. Under clear conditions, targets can be easily identified and effectively engaged. …

All modern forces depend on unimpeded access to, and use of, the EM spectrum in conducting military operations. Therefore, there is a requirement to gain and maintain an advantage in the electromagnetic spectrum by countering adversary’s systems and protecting one’s own systems. Adversary can disrupt and degrade the navigation systems …

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …
