    After looking more closely at the video, the power density in the near-field has to be revised.

    An 1 m dish has a surface area of about 0.75 m^2, so the maximum power density in front of the antenna is around 300 W/m^2. This is above the allowed limits for occupational exposure.

    The "hypothetical chicken" would cook in a somewhat shorter time in the near-field.

    Eye damage from concentrated microwave radiation is real, but it takes power densities
    orders of magnitude above what can be achieved in front of a realistically sized
    aperture antenna.

    The documented cases have been related to looking into waveguide feeds, and to the infamous incidents related to deep-heat treatment of sinusitis by microwave heating that was - briefly - tried in the 60s.

    OK, I'll put a sign on it

    Do not look into waveguide with remaining eye

    Either way, in a vacuum, the chicken is a dead duck.:oops::rolleyes:

    Dr. Carpenter claimed to cause cataracts in monkeys with microwave energy but in his initial report failed
    to mention that the level was so high it killed the animal.

    If slow cooking, I prefer to smoke a brined chicken over pecan and apple wood.

    nothing beats fresh armadillo or possum road kill, on the radiator of a '54 Chevy for 60-70 miles.

    If 10 Ghz bounced off of the moon, It bounced off of the American Flag pole.

    Or the remnants of a couple of Apollo landers...
