Now you'll be able to actively attract the waves!!

The 2.4GHz wavelength is about 12 cm. I used to use 23cms with my Radio amateur 
class A licence with slow scan TV primarily up to a few years ago.

Anyway, the wave length is around 10 centimeters for 3GHz (if my memory is 
correct L=c/f), so one doesn't need plain metal.
