Spectrum congestion is a growing problem. It increasingly limits operational capabilities due to the increasing deployment and bandwidth of wireless communications, the use of net-centric and unmanned systems, and the need for increased flexibility in radar and communications spectrum to…
Navies of various countries have announced making their warships and submarines propelled with an electric propulsion system. Instead of driving the ship’s propellers directly, diesel engines turn electric generators, which in turn power electric motors that drive the propellers. This arrangement…
For NATO forces, the Electromagnetic spectrum (EMS) is an essential part of military operations, so much so that many Allied leaders now see the EME as an operational environment and a part of the battlespace where friendly forces manoeuvre in…
Despite making reductions in their arsenals, both the USA and Russia have extensive and expensive programmes under way to replace and modernize their nuclear warheads, missile and aircraft delivery systems, and nuclear weapon production facilities. The Nuclear Race between US,…
Modern warfare is increasingly dependent on microelectronics capabilities that sense the environment, convert the signals into data streams, process the information, and generate a response. In this sense, Aerospace and Defense (A-D) systems are quite similar to commercial systems that…
Assaults by firearm kill about 11,000 people in the US each year, which translates to a roughly 1-in-370 lifetime chance of death from gun violence. That’s almost 50% more likely than the lifetime odds of dying while riding inside a…
Sonic weapons employ extremely high-power sound waves to disrupt or destroy the eardrums of a target and cause severe pain or disorientation. This is usually sufficient to incapacitate a person. Less powerful sound waves can cause humans to experience nausea…
The increased commercialization of drones is increasing the risks that these drones can be used by terrorists and criminals. The small drones such as a quadcopter or model airplane are readily available and it is highly probable that existing technology…
Muons are subatomic particles that behave a lot like electrons but are around 200 times heavier. As the US Department of Energy explains, “Muons created in the atmosphere constantly hit every inch of the Earth’s surface and pass through almost…
The emerging field of printed electronics requires a suite of functional materials for applications including flexible and large-area displays, radio frequency identification tags, portable energy harvesting and storage, biomedical and environmental sensor arrays, and logic circuits. To enable these…
