They’re selling defence equipment to countries, it wouldn’t help their cause if this is just smoke and mirrors. It either works or it doesn’t.

  I’m intrigued. Elaborate?

  If you read the entire article, you’ll find a mention of an audience member pointing at a drone. Remarkably, the device/weapon was able to precisely bring that drone down without affecting any of the nearby drones. Clearly, they have something working for them. I can only imagine that it would be significantly more challenging than simply throwing a very wide EMP. Controlling an EMP is the seemingly impossible task, and they managed to succeed.

    To be fair, they'd be able to do that even more easily with a drone show (ie remotely controlled drones).

    This is not EMP. It is just a high-power microwave transmitter, made with gallium nitride field-effect transistors. Like any microwave transmitter, it can use a directional antenna. If the antenna is big enough, it can have a narrow enough transmitted microwave beacon to intercept only a single drone. The GaN FETs enable a higher transmitter power at whatever high frequency they are using. At lower frequencies, a 70-kW power was already easily achievable in the past. The higher frequency allows a precise aiming of the microwave beacon with an antenna of reasonable size.

      I believe they're using a phased array grid of emitters to electronically steer the microwave, not just a normal directional antenna. This means the antenna doesn't need to physically move to change what is pointing at. (within some bounds)

Really. A British fraudster managed to sell $20 golf ball finders as bomb detectors for thousands of dollars each to various militarys. He got away with it for quite a while. https://www.bbc.co.uk/news/uk-29459896 https://www.bbc.co.uk/news/uk-29459896
