The article explains the physical mechanism - or at least the area in which it applies: At the vanguard of a new field of study that came to be known as bioelectromagnetics, he found what appeared to be grave nonthermal effects from microwave frequencies—the part of the spectrum that belongs not just to radar signals and microwave ovens but also, in the past fifteen years, to cell phones. (The only honest way to think of our cell phones is that they are tiny, low-power microwave ovens, without walls, that we hold against the sides of our heads.) Frey tested microwave radiation on frogs and other lab animals, targeting the eyes, the heart, and the brain, and in each case he found troubling results. In one study, he triggered heart arrhythmias. Then, using the right modulations of the frequency, he even stopped frog hearts with microwaves—stopped the hearts dead. also how modulated microwaves assit in breaching the blood - brain barrier In a study published in 1975 in the Annals of the New York Academy of Sciences, Frey reported that microwaves pulsed at certain modulations could induce "leakage" in the barrier between the circulatory system and the brain. Breaching the blood-brain barrier is a serious matter: It means the brain's environment, which needs to be extremely stable for nerve cells to function properly, can be perturbed in all kinds of dangerous ways. Frey's method was rather simple: He injected a fluorescent dye into the circulatory system of white rats, then swept the ­microwave frequencies across their bodies. In a matter of minutes, the dye had leached into the confines of the rats' brains.
