Researchers in China have engineered a cloaking device that can make drones entirely invisible to electromagnetic sensors during flight.

Explained in the simplest way possible, the drone is undetected by sensors because of its onboard-processing system that detects the sensors and then alters the surfaces outside the drone to make it undetectable.

Unfortunately, the drone is still easily visible to the naked eye, but researchers say the technology will only become more advanced.

Researchers: “The age of intelligent cloaks and intelligent metasurfaces is just dawning. Endeavors in achieving this goal have been embodied throughout streamlining photonics design, capturing latent physics, and automating metadevices.”
