The links would have to be quite a bit smaller than that, because the frequency is much higher than the 2.45 GHz (a wavelength of 12.24 cm) of a microwave oven.
Think an aluminum foil suit, something like a space blanket but continuous and all surrounding, with a metathesized visor, It would not need to be grounded. Anything completely surrounded by a conductor sees no electric fields inside. (For non DC fields, and a less than perfect conductor, there are magnetic and other effects which require the conductor to have some thickness. I would *guess* (but an educated one, since I am an EE) that at that high a frequency the thickness required for structural/mechanical reasons would be more than sufficient.
Yea it's a gun alright, in the same sense that a 155 mm howitzer is a gun. Kinda big to be carrying around with you. But that could change. Although making it smaller means less antenna gain, and thus lower power on target. You could compensate by increasing the transmit power, but that would be hard on batteries. Still if can live with much shorter ranges, yould could still get the effect... I think.. would have to run the numbers, if I knew the starting point numbers for this device.
Thanks for the correction. I am woefully ignorant in electrical engineering.
How about a dust? If you could manufacture tiny corner reflectors the size of dust grains and suspend them in the air in front of the gun, they would deflect and/or absorb the microwave energy in the beam...
Corner reflectors work pretty much at all frequencies down to those whose wavelength is comparable to the size of the reflector. Thus you don't need to make them that small. Ferrite dust might make a good absorber, but so would a water spray, the water spray would also reflect pretty well at those frequencies.
