Microwave energy

√A study commissioned by the US State Department has found that “directed” microwave radiation is the likely cause of illnesses among American diplomats in Cuba and China.

√The health effects were experienced by about two dozen Americans affiliated with the U.S. Embassy in Cuba as well as Canadian diplomats and personnel at the U.S. consulate in Guanghzhou, China, in early 2017.

√The study found that “directed, pulsed radio frequency energy appears to be the most plausible” explanation for symptoms that included intense head pressure, dizziness and cognitive difficulties.

√It found this explanation was more likely than other previously considered causes such as tropical disease or psychological issues.

√ The study, however, did not name a source for the energy and did not say it came as the result of an attack.

√Microwaves are defined as electromagnetic radiations with a frequency ranging between 300 MHz to 300 GHz while the wavelength ranges from 1 mm to around 30 cm.

√ They fall between the infrared radiation and radio waves in the electromagnetic spectrum.

√Metal surfaces reflect microwaves.
√ Microwaves of certain frequencies are absorbed by water.
√ Microwave transmission is affected by wave effects such as refraction, reflection, interference, and diffraction.
√ Microwaves can pass through glass and plastic.

√“Microwave weapons” are supposed to be a type of direct energy weapons, which aim highly focused energy in the form of sonic, laser, or microwaves, at a target.
