DARPA Ditto developing artificial intelligence (AI) and machine learning based surrogate models to speed design of military systems

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 more accuracy, speed, and agility than traditional tools.  Yet operational …

Nanotechnology enhanced Supercapacitors, including Graphene and carbon nanotubes (CNTs) provide superfast battery charging in electric vehicles to wearable electronics

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 solutions  such as electric vehicles with low exhaust emissions. However the …

Race for faster, high performance System on Chip (SoC) for 5G, mobile computing, Smartphones, and IoT

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 integrates a microprocessor with peripheral circuits and memory, an SoC …

Extremely Low Frequency and Very Low Frequency (ELF/VLF ) Communications for Underground, Underwater, and Hypersonic Flight

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 signals have large EM wavelengths that can penetrate the plasma …

GaN on Diamond for next gen Power Devices and High-Power RF applications

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 move to a new element. GaN is a wide bandgap, …

Countries integrating Over-The-Horizon (OTH) radars into air defence networks to detect and track stealth Aircrafts, Aircraft carriers and hypersonic missiles

The signals of Conventional microwave radars propagate in a straight line and cannot detect objects beyond their line of sight.  The maximum range of these radars is limited by the radio horizon – slightly far away than the optical horizon. OTH radars use very long wave lengths with special properties …

Multistatic Sonar Technology has become key to Anti Submarine Warfare (ASW) operations

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 of a few years. The threat from submarines is serious …

Compact Electronic noses can monitor air quality, diagnoze diseases to biohazards like covid-19, explosives and nerve gas

Government and local law enforcement agencies have employed canines for decades to sniff  explosives and such banned goods as fresh produce, exotic wildlife, undeclared currency and illicit drugs.   Now researchers are developing electronic noses imitating the sense of smell of humans and animals especially dogs. The smells are composed of molecules, …

DOD regards Electromagnetic Spectrum (EMS) as a critical battlespace in its own right, and launch it’s Electromagnetic Spectrum Dominance Strategy

Successful military operations depend upon freedom of action in the warfighting domains of air, space, ground, sea, and cyberspace. Today, effective command and control and situational awareness depend upon radio communications and sensors. Domination of the electromagnetic spectrum (EMS) enables joint force commanders to gain tactical, operational, and strategic advantage …
