![]() So here’s how the calculation shakes out: We want to know the minimum output power of a 2.45 GHz microwave generator able to produce at least 1 W/cm 2 inside a house 150 ft away, through at least one wall. Also, the incident provides a means for making a ballpark estimate of range we might say 150 ft from the street to the woman’s home would be a reasonable guess. The implication is that the microwave generator was small enough to fit in the van. It has also been reported that the wife of a member of the Cuban embassy staff once looked outside her home after hearing disturbing sounds and had seen a van speeding away. There’s no data in the open literature on the threshold of microwave power that causes human brain damage, but the researchers suggest a minimum intensity of 1 W/cm 2 impinging on the human head–using 50-µsec pulses on a 7 kHz repetition rate–might be a good place to start. One paper in this area published in Frontiers of Neurology points out experimenters were able to kill rats by exposing them to 2.45 GHz microwaves with a field intensity of 1,000 W/cm 2. So sufficiently interested individuals can do a little research and draw their own conclusions. Fortunately, there is open research on directed energy effects. Fortunately, the temperature rise is tiny (microdegrees) and the pressure wave is far too weak to injure tissue unless the microwave power density is huge.Ĭritics have pooh-poohed the directed energy conclusion, claiming a microwave generator big enough to cause tissue damage would stick out like an NBA center at a jockey convention. ![]() The expansion launches a pressure wave that propagates throughout the skull to the inner ear, potentially causing clicking or buzzing sounds. When a human head absorbs a pulse of RF energy, a rise in temperature causes tissue inside the head to expand slightly. ![]() The directed microwave energy theory rests on what’s called the microwave auditory effect. ![]() Panel members could not rule out the possibility that the whole episode was a case of mass hysteria but considered the idea unlikely. directed microwave energy) was the most likely cause. Though the panel reached no definitive conclusion, it found pulsed RF (a.k.a. The National Academy of Sciences recently released its conclusions about what sickened dozens of American Embassy diplomats in Cuba, a phenomenon dubbed the Havana Syndrome. ![]()
