In magnetic memories, information (for example, a collection of bits) is stored as clusters of spins, which are either an up or a down (or put differently, a one or a zero). These spin clusters, which form the basis of magnetic memories, become less stable when reduced in size. Magnetic …

Biofouling is one of the main problems faced by every type of ship at the sea. Marine growth such as barnacles and mussels have been the reason for problems such as decreased ship efficiency, corrosion etc. Biofouling not only sticks to the external surface of the ships but also gets into …

Military platforms—such as ships, aircraft and ground vehicles—rely on advanced materials to make them lighter, stronger and more resistant to stress, heat and other harsh environmental conditions. Currently, the process for developing new materials to field in platforms frequently takes more than a decade. This lengthy process often means that …

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 …

The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. LiFi works by switching LEDs on and off within nanoseconds to communicate …

The emerging quantum revolution offer revolutionary capabilities for military from quantum creptography for hack proof communications to High-precision atomic clocks that can enable timekeeping for navigation and communications with GPS-like performance even in GPS-denied environments. Another important area is quantum computing based on quantum bits, or qubits, which can represent …

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, …

Digital cameras use a focal plane array (FPA) to convert light energy into electrical energy that can be processed and stored. The FPA is a two-dimensional (2-D) array of photodetectors (or pixels) fabricated on an electro-optical material. Modern digital cameras contain FPAs that have pixel counts on the order of …
