The viral diseases like Zika. Ebola. Dengue. Influenza. Chikungunya pose serious health threats to U.S. troops, as well as to civilian populations in the United States and around the world, says DARPA. Vaccines exist for but a few of these infectious diseases. And since these viruses have an uncanny ability …

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 …
