  • Dear Sir, I have an immense amount of problem with white noise and an alternating sound in my home. There is a tower of some sort across the street from me, and I have 7 transformers around my house in a triangle formation. 3 transformers are on the East side, 3 are on the West side and one on the South side. Would a metal comb like the one in the film, only much larger solve my problem in your opinion?

  • The most interesting part is from 0:50. How the hell the polarizer (metal comb) can "unpolarize" the waves to make it reappear again? o_O Can someone explain it for me?

  • @Saskachewan Think vectors. A polar filter takes the component vector of the polarized light traveling through it. The polarization changes as the light passes through. So if the filter is perpendicular, the component vector is 0. If it's 45 degrees off, only about 70% of the light passes through. Another 45 degree change results in half of the original light making it through both.

  • @Libertarianist Hi, can these microwave emitters be adjusted for frequency and wavelength, or are these here at a set frequency and is this simply showing how one can polarize or direct the flow of EM ?

    Regards

  • This is a demonstration of polarization, the effect occurs with all frequencies, but shorter wavelengths require combs with finer teeth.

  • @Libertarianist Hi, thanks, but can one manipulate the frequency of microwaves in some sort of transmitter or emitter?

  • @Libertarianist Yes for polarization effects, one could use fine mesh maybe,. or optical s, even camera filters could do it, i would think it would depend on the structure of the materiel the waves pass through

  • !!!

  • yea but ummm... you dont think that the signal was modulated with a triangle wave form?

    Hah if MIT is spreading lies then I'm not sure I want to know the 'truth' ...your truth, that is

  • cant you delete this guys comments?

  • @m1ndcontroller The triangular signal is used just to modulate the microwave signal ( wich is a sinusoidal wave) to show better the amount of the microwave that passes through the filter to the receiver.. Insted of triungular signal you can use any signal (including your voice) to modulate the microwave carrier wave...think of a radio receiver ...

  • What is the output power and frequency of the microwave emitter? And does it use a Gunn diode?

    Thanks, Carl
