Over the last 15 years, the U.S. military has increasingly been called upon to face complex operational environments (OE) and diverse enemies. The modern hybrid or irregular conflicts are dominated by complex human dynamics with intertwining political, territorial, economic, ethnic, and/or religious tensions. DARPA explains, “The US military increasingly operates in …

The adversaries are fielding increasingly sophisticated networked and agile systems, RF sensing and communications systems, including short-range tactical communications, long-range command and control (C2) communications networks, networked defensive systems, and RF seekers. This is partly due to rising commercial investments in RF materials, components, and subsystems thereby reducing the cost …

Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum or directed energy to control the spectrum, attack of an enemy, or impede enemy assaults via the spectrum. The purpose of electronic warfare is to deny the opponent the advantage of, and ensure friendly unimpeded access to, …

The extraordinary promise of quantum technology—depend on quantum “entanglement,” in which the physical states of two or more objects such as atoms, photons or ions become so inextricably connected that the state of one particle can instantly influence the state of the other—no matter how far apart they are. Today, …

A metal foam is a cellular structure consisting of a solid metal (frequently aluminium) with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam). The defining characteristic of metal foams is a high porosity: typically only 5–25% of the …

Silicon is predicted to remain as the fundamental material for the micro- and nano-electronics industry and ultra large scale integrated (ULSI) circuits despite the ever-growing research devoted to other materials and their nano structured variants.   Silicon Nanowires (SiNW) are one of the members of silicon nanostructure family, which have …

In recent years there has been a major scientific thrust to harness quantum phenomena to increase the performance of a wide variety of classical devices ranging from computation to sensing, and considerable progress has occurred in the analysis and design of photonic-based quantum sensors (e.g. quantum radar and quantum lidar). …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing, is defined by ASTM International as the process of joining materials together, layer by …

Lidars (Light Detection and Ranging) are similar to radars in that they operate by sending light pulses to the targets and calculate distances by measuring the received time.  The  key advantages of  LIDAR is  its superior accuracy and its ability to see through masking items, such as leaves, trees, and …
