How to Build a Circuit to Absorb or Capture Electromagnetic Waves Efficiently?

Hi to all
Im looking for an circuit which can attract electromagnetic wave,can you help?

Hi there,

Honestly, I haven't heard or known anything like this. Maybe Im just wrong. But a electromagnetic wave generator perhaps, Im sure there are alot of references for this.

Well, the best way to do this is to put a nice heavy black hole next to it :D

In all seriousness though, electromagnetic waves can't really be attracted the best you can do is offer a more permeable path or put a big receiver(dish or otherwise).

It is no longer a 'circuit' problem as well, it falls more into the physics of waves and antenna construction which I'm not very familiar with.

Perhaps you can give more details on the frequency of the signal you want to listen to?
