Electromagnetic Spectrum

The US Department of Defense evaluates that the military’s traditional intelligence sensors are not always optimal for the tasks that have become more and...

Wireless networks are expected to support far more than smartphones in the coming decade. Autonomous vehicles, industrial automation, critical infrastructure, and AI-driven services will...

Society demands continuous implementation of new transmission systems due to ongoing development of communication technologies. These systems work by emitting electromagnetic waves. As a...

GPS signals don't penetrate very deeply or at all in water, soil or building walls, and therefore, can't be used by submarines or in...

Engineers from two universities, Ruhr-Universität Bochum and University of Duisburg-Essen, have developed novel signal processing methods for imaging and material characterization with the aid...

Modern technology depends on precision, yet many critical systems operate in environments filled with invisible magnetic noise. Power infrastructure, medical imaging, aerospace platforms, and...

The risks of an electromagnetic pulse (EMP) attack simply cannot be overstated. A single powerful charge detonated at a high-enough altitude over the continental...

Satellites have become a critical part of modern military operations, providing communications, navigation, intelligence and targeting data to forces around the world. As dependence...

Conventional firearms rely on chemical propellants, producing noise, flash, and visible signatures that can limit their use in certain operational scenarios. In law enforcement...

A new EU-funded project has demonstrated a prototype device that can control and stop non-cooperative vehicles posing a threat, by disrupting the functioning of...

With nearly every aspect of modern life relying on computers and electronics, the dangers of electromagnetic pulse (EMP) weaponry cannot be overstated. An EMP...

US Air Force officials are working with microwave experts to conduct experiments with high power electromagnetic (HPEM) technology. The work offers the potential to...

Written By Or Shalom Over the past decade—and particularly in recent years—the lower airspace domain has evolved from a regulatory gray area into one of...

With the goal to equip its armed forces with emerging and disruptive technologies, the Latvian MoD will invest some $1.4 million in three innovative...

Sharing the limited resources of the electromagnetic spectrum with civilian organizations is one of the challenges faced by military forces. An advanced solution currently...

The rapid proliferation of drones has created a new challenge for military forces and critical infrastructure operators. Modern threats range from small commercial quadcopters...

Maintaining reliable communications in congested or contested environments remains a growing challenge for military and unmanned systems. Most fielded radios still rely on omnidirectional...

A world record was set for the largest drone swarm ever deployed during an aerial show in China. A swarm of 1,180 coordinated drones...

Congested bandwidth is challenging. The recent concern about 5G deployment near US airports focuses on the problem of radio interference. Beyond the 5G issue,...

Conductive Composites, a small Utah company, has developed an extremely thin, flexible material, to shield from electronic emissions and electromagnetic pulses. Beyond traditional network-penetration, novel...
