"Superlens" quite interesting

The concept of the 'Superlens'  for wireless power transfer is quite interesting. This could be very useful for charging of electrical vehicles as they can be charged while on the move by the proximity magnetic field .

I think a similar approach has been used for the driver less electric vehicle , I saw , on some other blog .

Agreed, a technology that can boost the wireless transfer of power involves a whole range of possibilities. We shall see how this plays out and where it ends up being used.

It's a clever design and looks like it lends itself quite well to their next enhancement -- the addition of dynamic tuning. If implemented in a smaller & thinner form factor, this approach could also do wonders for wireless charging pads for mobile devices.

Meta-material performance is disappointing

I read the paper.  The peak simulated power transfer efficiency is 6% at about 14 cm.  If there were no fancy metamaterials, it would achieve 6% efficiency at 10 cm, and the efficiency is much higher at smaller distances.

I don't see it being more than a laboratory curiosity for a long while.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
