US DOD’s Advanced Extremely High Frequency Satellite (AEHF) is a joint service satellite communications system that provides global, survivable, secure, protected, and jam-resistant communications for high priority military ground, sea, and air assets. The AEHF system provides joint, interoperable, assured connectivity for warfighters in operations in all levels of conflict–a …

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 Joint Light Tactical Vehicle (JLTV)  is an Army-led, multiservice initiative to develop a family of future light tactical vehicles to replace many of the High Mobility, Multi-Wheeled Vehicle (HMMWV), which has been in service since 1985. The unarmored Humvee were found vulnerable to IEDs in Iraq and Afghanistan where hastily added …

The Hellfire missile is the primary 100-pound (45 kg) class air-to-ground precision weapon having multi-mission, multi-target precision-strike ability, and can be launched from multiple air, sea, and ground platforms, including the Predator drone. But the most common platform is the AH-64 Apache helicopter gunship, which can carry up to 16 …

Controlled Flight into Terrain (CFIT) is the #2 leading cause of General Aviation fatal accidents involving the loss of life. There have been over 9,000 deaths due to CFIT since the introduction of commercial jets.  Between 2000 and 2009 approximately 961 people died worldwide as a result of CFIT, the …

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 …
