would the rf detector itself not be the source of the rf waves? when stores use those anti-theft tags like at the mall, say, it's not like the tag itself is emitting waves. I assume it's the detectors you walk through resonating with that tag that sets them off. plausibly the same thing is happening here.
sounds like schizo-something or other.
Tags are very simple RFID chips with antennas that are powered by the received RF waves from the anti-theft transmitter and are echoing them back to it.
The bugs detectors work differently. They are specifically set to get triggered by devices self-emitting specific RF signals in a very low range vicinity.
They may have left the tag on the implant during surgery. Everything in surgeries are tagged now and have to be scanned for inventory and to supposedly keep the idiot surgeons from leaving sponges and clamps in people. If they didn't scan it at the beginning of surgery, they wouldn't get the warning about it later. I would have hoped the tag was on the wrapping of the device but who knows.
ah, interesting. i had no idea.
so, provided there's an RF pulse coming out of this guy's leg, then why. gotcha.
It could be easily answered with an X-Ray.
Could a stainless or titanium mesh act as an antenna?
I get the bug sweeper is passive but could a mesh be reflecting another signal or is that just not physically possible?
Maybe.
