Re: LF: Very Annoying Aricle

Andy,

On the webpage you refer to I read:
---------------------
To overcome this
problem, the team investigated a special class of
"non-radiative" objects with so-called "long-lived
resonances". 
When energy is applied to these objects it remains bound to them, rather
than escaping to space. "Tails" of energy, which can be many
metres long, flicker over the surface. 
"If you bring another resonant object with the same frequency close
enough to these tails then it turns out that the energy can tunnel from
one object to another," said Professor
Soljacic. 
---------------------
Somehow this sounds familiar to me (in particular the last sentence).
Maybe from the manual of my dip-meter ...
A more known word for "long-lived resonances" may be
"high-Q LC circuit".

Further I don't read anything about possible absorbance (= reduced
efficiency, maybe unwanted heating) by the many object that will be near
the "long-lived resonances" in a real-world situation.
I guess the computer simulation mentioned assumed a situation somewhere
in outer space.
