U of T developing radar 'invisibility cloak'
Toronto Sun ^ | November 12, 2013 | Jenny Yuen

TORONTO - Harry Potter, eat your heart out.

A University of Toronto professor and a PhD student have developed a new invisibility cloak — at least on radar.

Computer engineering Prof. George Eleftheriades and PhD student Michael Selvanayagam are now in talks with the Canadian military to see if their new approach to making things invisible to radar can be applied in the field.

It could possibly hide military vehicles or have uses in surveillance operations.

In addition to the Armed Forces, it could possibly be used to help ease the movement of signals from cellular base stations.

“We ‘see’ a physical object by detecting electromagnetic waves scattered from the object,” Eleftheriades explained Tuesday. “A device that can ‘correct’ or cancel that scattering would take the notion of a magic invisibility cloak from the realm of science fiction to reality.”

In order to cloak objects from radar, the researchers surround it with many small antennas that radiate an electromagnetic field. The radiated field cancels out any waves scattering off the object, making it appear “invisible.”

Eleftheriades and Selvanayagam have been working on a functional invisibility cloak since 2006, but earlier efforts yielded no practical uses.

The system can also alter the “radiowave signature” of a cloaked object, making it appear bigger, smaller or even shifting it in space.

Perhaps Toronto mayor Ford would like to give it a whirl.

Will it work on speed trap radars??

Yesterday, upon the stair,
I met a man who wasn’t there
He wasn’t there again today
I wish, I wish he’d go away...

When I came home last night at three
The man was waiting there for me
But when I looked around the hall
I couldn’t see him there at all!
Go away, go away, don’t you come back any more!
Go away, go away, and please don’t slam the door... (slam!)

Last night I saw upon the stair
A little man who wasn’t there
He wasn’t there again today
Oh, how I wish he’d go away...

Dictators are notoriously paranoid. Can you imagine if they suspect that something is there but they just can't see it?

Sounds like what ECM (electronic counter measures) aircraft have been doing for years.

To discuss that, we really must insist on the Cone of Silence.

Cloaking is child’s play. A transporter is the technology that will change the world.

Similar, I think, but this should have advantages. The Salisbury screen has to be built with a certain wavelength radar in mind, and is only going to be effective against that. If you are emitting an EM field to create the destructive interference, then you can easily emit waves to match any wavelength radar that you need to counter.

Interesting! With the ability to make yourself larger, smaller, and dart back and forth on the radar screen, I wonder if tests like these were happening when someone was reporting a UFO on their radar?

We need to put a cloak on Obamacare and make it go away.

I think he’s from the CIA.

Didn’t Holly think he saw a bunch of black holes and it turned out to be dirt on the radar?

Given that the cloak works by cancelling out arriving light, the only thing that springs immediately to *my* mind is the bit about the primary thing about black holes is that they’re black.
