When I was employed, I worked in the field of applied physics. I specialized in low energy plasma processes, electron and Xray analytical methods, flame and toxic chemical detection. My interest in that discipline has not waned since my retirement. The topic of the “Havana Syndrome" caught my interest immediately when it appeared in the media a few years ago, shortly after my own visit to Havana. I wanted to put my two cents worth about this threat out for others to consider.
The reason the "Havana Syndrome" is so named is that Havana was the first location at which it was reported. Members of the US Diplomatic Corps residing in or working in the US Embassy in Havana reported the mysterious symptoms and associated them with strange sensations of sound and other discomforts. Some reported permanent disability from the experience. The name ”Havana Syndrome" has NOTHING to do with who might be perpetrating the phenomenon.
I have been saying that the phenomenon was caused directed energy, either radio frequency/microwave or acoustic/ultrasonic, ever since the phenomenon was first observed. I even contacted the NSA regarding my views on the origin of this, including the possibility that someone is using high powered ultrasound, to be modulated by pressure variations caused by speech within a room, to listen in on conversations within that room. There is published documentation about this available.
Ultrasonic energy strong enough to allow this process to work would indeed be painful to those in the field.
The ultrasonic spying possibility is intriguing to say the least. The response from NSA was “How do you know about this”? My response was that I did not “know” anything about this but that I was simply speculating based on my extensive past experience with radiation, RF energy and sonic energy. That was the end of the conversation.
In addition, a few years ago, on public media, our military announced development of "non-lethal weapons" for crowd control among other things. Specifically, a device using electronics similar to a microwave oven, fed a very high gain high directivity antenna. This device was "tuned" such that its microwave energy would be only absorbed by the top for layers of skin, producing immense pain but no permanent damage to the party at which it was aimed. It is not a giant leap to think that someone might change the frequency, and power of this type of device, to cause different, more permanent effects.
Either process, and likely other possible directed energy processes could easily cause internal damage to living organisms. That is why microwave ovens have interlocks on the doors.
One would think that a Department of Defense with a trillion dollar budget could pop for a few spectrum analyzers, both RF and Acoustic, to continuously monitor the energy fields around sensitive locations. energy strong enough to bring about deleterious biological effects should be far stronger than typical RF or Acoustic fields so background noise should not cause false positive detection. Even a relatively simple broad band RF or Acoustic field strength meter could detect pulses if they were too short to be caught by scanning spectrum analyzers. Also, a Fourier Transform type of spectrum analyzer should allow detection of even short duration pulses.
Is anyone doing anything about this, REALLY?
