Wanted to understand the physics behind usage of passive
antennae and matched load combination, to absorb, control and
reduce the Electromagnetic-Field (s.a. due to microwave radiation
from cellular phone towers), within a confined area (s.a. a room).
Also, does the shape / size / material used for the antenna have a
role to play ? If this kind of absorption does work, what might be
the range / shape of the area that such a device can reduce /
remove...
