| It may be possible to build a "Havana Syndrome" microwave weapon by utilizing the microwave auditory effect with a modulation at the resonant frequency of the target's skull. https://en.wikipedia.org/wiki/Microwave_auditory_effect It this is actually covered in Russian Patent No. 2,526,478: "Method and Device of Microwave Electromagnetic Impact at Trespasser" https://patents.google.com/patent/RU2526478C2/en "The technical result is achieved by the fact that it is proposed to use directional radiation modulated by amplitude of the microwave electromagnetic waves. The impact on the intruder is due to the occurrence of painful mechanical thermoelastic phenomena in individual elements of the human auditory apparatus at their resonant frequencies" "Resonance phenomena in the 'radio sound' are due to the size of individual elements of the human auditory apparatus and are observed in the range of modulation frequencies of 6 ... 12 kHz." "Claims: 1. The method of microwave electromagnetic exposure to the intruder, characterized in that the effect is carried out by an amplitude-modulated microwave electromagnetic field with a changing modulation frequency, while the amplitude modulation frequencies are taken in the range of mechanical resonant frequencies of the intruder's head and individual elements of his hearing organ. 2. A microwave device for electromagnetic influence on an intruder, comprising a microwave generator with a radiating antenna, characterized in that an amplitude modulator and a low-frequency tuner are introduced into it, configured to tune to the mechanical resonant frequency of the intruder's head and individual elements of its hearing organs. The output of the low-frequency tuning unit is connected to the control input of the amplitude modulator, the output of which is connected to the control input of the microwave generator." http://www.gbppr.net/mil/havana Note the resonant frequency of the human head is in same frequency range as those crickets... |
A more thorough version here if anyone haven't read it before.
I mean, maybe its possible such weapon exist, but if these cases are really caused by it, why not US can't find any clues? Its very hard to imagine due to the whole level efforts input into the investigations, several years, multiple continents, and still no clues. So I guess, its still possible some weird things happened, like supernatural?!
