Hi Folks!

This report says they achieved an output in EXCESS of
what they put in. Is it possible light waves
subjected passed through or into a certain shape or
made to move a certain pattern, can be intensified to
produce an overnunity effect?

BIG LIGHT THROUGH LITTLE HOLES. Baffles with apertures
smaller than the wavelength of a particular light wave
aren't supposed to transmit much of that light.

So it came as a surprise to Thomas Ebbesen at the NEC
Research Institute in New Jersey when he shone light
through sub-wavelength arrays (150-nm holes in a film
of silver, coating a quartz substrate);

at selected wavelengths, plentiful amounts of light
(with wavelengths up to 10 times the size of the
holes) came out the other side.

Taking into account the area of the holes relative to
the size of the light beam, the light was in some
instances being transmitted with an efficiency of
GREATER THAN 1.

The leading explanation is that the light is making
its way through the holes in the form (or with the
assistance) of surface plasmons, non-radiating
electromagnetic disturbances arising from the
collective movements of electrons at conductor-
insulator interfaces.

The researchers believe that for device applications
their arrays, which transmit light at special
wavelengths, will complement so-called photonic
crystals, which exclude light at special wavelengths.
