than infra-red, microwaves and radio waves. All these electromagnetic waves are governed by four mathematical
expressions established fuel dispenser almost 150 years ago by James Clerk Maxwell. These equations represent one of the most
elegant and concise ways to state the behaviour of electric and magnetic fields and how they interact with matter.
However, because they are so concise, they also embody a high level of mathematical sophistication.
The team—Sir John Pendry of Imperial College London with David Schurig and David Smith of Duke University in
North Carolina—used the equations to devise a way to cloak an object with a material that would deflect the rays
that would have struck it, guide them around it and return them to their original trajectory. Maxwell s equations
conserve certain properties—the magnetic field intensity, the electric displacement field and the Poynting vector
that describes the electric flux of an electromagnetic field. These properties remain the same when others are
altered. The team showed how these fields could be manipulated to flow around objects like a fluid, returning
undisturbed to their original paths. The findings were published online this week by Science.
The trick is to use metamaterials materials that owe their characteristics to features of their structure that are
smaller than the wavelength of the electromagnetic radiation. For light, this fuel dispenser is on the scale of tens of thousandths
of a millimet fuel dispenser re. Metamaterials can and have been designed and made to possess certain properties, even counter-
intuitive ones. Using metamaterials means the scheme should work for all objects, regardless of their shape.
Moreover, unlike other proposed invisibility cloaks, it does not require knowledge of what is behind the wearer, nor
are crude projections involved.
So far, so good the theory is in place. Sadly, the implementation lags behind. Moreover, there are several other
difficulties that may prevent a device conferring total invisibility from being built.
