Engineers have long looked to origami and kirigami for inspiration when designing lightweight structures that can transform shape without relying on complex mechanical systems....

Modern military and civilian communications environments are becoming increasingly crowded. Drones, radios, sensors, satellites, electronic warfare systems, and wireless networks all compete for space...

The drone threat continues to evolve at a rapid pace. Explosive drones and loitering munitions have become some of the most significant threats facing...

As billions of devices connect to cloud platforms, industrial systems, and IoT networks, authentication is becoming increasingly difficult to manage. Most current systems rely...

Security labels, optical data storage systems, and environmental sensors often face the same limitation: once information is encoded, it remains static. Creating materials that...

Foldable structures are widely used in engineering because they can transform from compact flat sheets into larger three-dimensional forms. But most existing designs face...

Modern soldiers increasingly operate with multiple connected devices at once, such as radios, sensors, cameras, navigation systems, hearing protection, and digital battlefield applications. While...

Small drone swarms are becoming increasingly difficult to stop using traditional air-defense systems. Conventional remotely operated gun turrets usually rely on mechanically rotating toward...

Small unmanned aerial systems have become an increasingly common challenge for naval forces. Surveillance drones can track ship movements, collect targeting information, and operate...

The growing use of drones on the battlefield is creating a new challenge for air defense systems. Small, low-cost drones can operate individually or...

The growing use of inexpensive drones has created a major challenge for air defense systems. Small reconnaissance UAVs and FPV strike drones can be...

As air forces adapt to more contested environments, there is growing demand for platforms that can operate alongside manned aircraft while reducing risk to...

Drone threats at sea are becoming more frequent and harder to manage. Small, low-cost UAVs can be launched in large numbers, forcing naval forces...

The growing use of small drones is forcing a rethink in short-range air defense. Commercial quadcopters and improvised FPV systems are inexpensive, easy to...

Wireless networks are under growing pressure as more devices compete for bandwidth indoors. Offices, homes, and public spaces are increasingly crowded with Wi-Fi and...

Rescue helicopters operating in contested environments face a growing threat from infrared-guided missiles. While onboard warning systems can alert crews to incoming threats, they...
