Your latter concern is covered in the article: "But if it works as intended, the beam won’t ever contact anything but empty air. The system uses a net of lasers surrounding the beam to detect obstructions, like a bird or person, and it automatically shuts off transmission until the obstruction has moved on."
- NateEag 6y agoOP explicitly said, "The laser trips won't cover this." That may or may not be true, but you're bringing up a point they already addressed.
- biofunsf 6y agoOP explicitly said: “Even a horn has diffraction sidebands, and unless they're all at least 8dB down in all situations that's bad. The laser trips won't cover this.” I don’t really understand this. My guess is that they’re saying that besides the targeted microwave band, other high/low frequencies will be emitted (sidebands) and that these will diffract and be way outside of the directional beam that’s protected by the laser trip wire. I would assume the inventors have at least some explanation for this, but a fluffy article won’t go into those details.
- elihu 6y agoMaybe OP meant side-lobes? https://en.wikipedia.org/wiki/Side_lobe https://en.wikipedia.org/wiki/Side_lobe
- Zenbit_UX 6y agoA horn? Like a fucking rhino? Glad OP covered that use case, I was concerned.
- Emrod 6y agoAs you rightly noted, an article wont go into those details :). you are rising a valid point which we have addressed. Happy to explain if you PM me
