First I didn't know where to open new tread, so I open hear, if I put in wrong section please teach me where is the write place. As amateur in Physics I saw somewhere that with scalar waves you can communicate in transmitter-receiver way of course if resonance between t-r is good. Can we, and how interfere this communication (is there some active or passive measure). On net I see example where faraday cage is used as isolator for hertz waves, and if receiver is also in F. cage can we put let say another stronger receiver to retake control over the "old" receiver with "new" one if this new receiver establish better resonance. Also I would that you point me in write direction if I captured something wrong, and would appreciate to give me some web links to learn about the topic.
