Polish scientists have developed a novel electromagnetic counter-drone system that can neutralize hostile UAVs without explosions or physical impact. Created by researchers at Gdańsk University of Technology, the solution has been dubbed an “invisible shield” due to its ability to stop drones without visible or destructive effects.
The system, called STRATUS, generates brief but powerful electromagnetic pulses that disrupt the internal electronics of unmanned aircraft. By targeting critical onboard systems, the pulses can effectively disable drones in mid-operation, offering a clean and precise alternative to traditional air defense or jamming solutions.
A key feature of STRATUS is its precision-controlled effector, which allows operators to tailor pulse intensity to the threat level. This capability helps maintain safe voltage thresholds, ensuring operator safety while minimizing collateral effects on nearby electronic systems and communications networks.
Developers say the technology is intended to safeguard high-risk and high-value sites, such as airports, energy facilities, military bases, and crowded public venues. As drone threats continue to evolve, STRATUS represents a promising non-kinetic approach to modern airspace protection and critical infrastructure defense.
