Fractal Antenna Systems: Fractal Antenna Systems' DRONE BLASTR Downs Drones by Sound Waves

- Fractal Antenna Systems, Inc. has unveiled Acoustic Resonance Mitigation (ARM), a pioneering technology that disables drones using directed acoustic energy. ARM works by emitting sonic, ultrasonic, and/or subsonic waves at a drone, thereby inducing vibrations and /or Prandtl layer instability that will lead to flight failure. Propeller blades are especially vulnerable to ARM's power, [...]
