Experimental results in backward and forward scattering for microwaves.
The normalized modulus (upper panel)of the magnetic field is measured along the median shown in lower panel. The frequency of the source is 3.550 GHz. One notes that the magnetic field intensity is reduced by 18 dB at the center of the cloak with a reduction up to 30 dB inside the inner disc. The field is enhanced inside the corona and its intensity in front and behind the cloak is close to what it would be in free space. Similar results hold in the cloaking interval [2.6,6]GHz, see Fig. 6.
