Bending Light

10/24/2011 4:03 AM

Do you think light could be bent by a specific type of material?

This is the solution to invisibility.

Light is already bent as it passes through the boundary of two materials with different refractive indices.

I mean in the case of total diffraction.

Go to you tube & search invisibility.

Sure I did

They dont specify the type of material.

Thats why I am here.

Gulsine,

Why don't you start over and tell us what you have researched so we don't give information you already know.

We can't read your mind. I had no clue if you had done any research at all.

Are you attempting to build something?

write a paper?

learn for the sake of learning?

What are your objectives?

It's probably commercially sensitive.

I become invisible if I drink too much tequila.

gulsine, go do an internet search for "metamaterials" and "negative index refraction". You will find that the "invisibility" material does not exist in nature (that we know) but has been invented and is the subject of some very interesting research.

gulsine, I admit I am curious.

First you wanted to make your car bulletproof, and now you want to make it invisible.

Tell us: Are you Batman, or just making him a new car?

Given the choice, I'd make this car disappear.

One of my early attempts at a chick magnet.

It truly is amazing I had any kids.

Actually, that car is a kid magnet. Nice job, Doorman!

These days I have a thought that invisibility is possible.

Sure they invented it and the guy who invented it is already invisible !

Just in case the invisibility experiment works partly, wouldn't it be prudent for gulsine to follow your advice to 'semper ubi sub ubi' ? You never know which part may remain visible....

Not sure where I saw this (maybe one of the Discovery Channels), but there has been some research into this subject. If I am correct it was being done in Europe at one of the energy labs who run super collider. Won't swear on that as I don't look'y so good any more.

One "solution" to invisibility, was an application of light. During WWII, the "gold-standard" of sub-hunter-killer aircraft, was a huge searchlight(maybe half the diameter of an engine!) stuck into the wing of a patrol bomber, to where the plane was "invisible" to the surfaced U-boat's air-craft-spotters until it was too late to avoid (dive/manuver) air-dropped bombs/depth charges from the patrol bomber. I don't know why the light wouldn't have been seen itself, but evidently not. --Lyn, was this the device that caused one U-boat to "surrender" to an aircraft? I don't know how THAT would be done(giving-up), as I don't think the plane in question, was a flying boat!
