A hydrophone is an underwater listening device, just as a microphone is used to detect sound in the air. Hydrophone detects sounds in the water and converts the acoustic energy into electrical energy by detecting changes in pressure in the…
Three decades ago, only a handful of major powers had effective submarine capabilities but, today, fleets in operation around the world are growing rapidly. Emerging superpowers, like China, can add naval capacity equivalent to a European country’s in the space…
In recent years organized crime in maritime regions has flourished, threatening both secure flow of goods from Exclusive Economic Zones (EEZ) and lives of participants in the marine operations. Security threats and humanitarian risks caused by trafficking (drugs, weapons, etc.),…
The military uses the electromagnetic spectrum — essential, yet invisible — to detect, deceive and disrupt the enemy while protecting friendly forces. As enemies become more capable and threats more complex, controlling the spectrum is increasingly critical. However, today’s electromagnetic…
DoD is exploring opportunities to incorporate autonomy, AI, and human-machine teaming into its weapons and operations. Whether as data-mining tools for intelligence analysts, decision aids for planners, or enablers for autonomous vehicle operations, these systems have the potential to provide…
An unmanned aerial vehicle, or UAV, refer to a vehicle that is able to fly remotely, either with some sort of controller or autonomously. An unmanned aircraft system, or UAS, includes not only the UAV, itself but also the person…
The rapid increase in global energy consumption and the environmental impact of traditional energy resources pose serious challenges to human health, energy security, and the environment; and reveal a growing need to develop new types of clean and sustainable energy…
A system on a chip or system on chip (SoC) is an integrated circuit (also known as a “chip”) that integrates all components of a computer or other electronic system on a single circuit die. Similar to how a microcontroller…
Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band…
Gallium nitride (GaN) is hot. Even hotter is a race to integrate GaN with other materials to boost GaN’s performance further. The power electronics industry has seen the theoretical performance limit reached by silicon MOSFETs and now needs to…
