Hi,

I have read in some research journels that metamaterials (or -ve ref. index materials) can be used in forming perfect lenses. I read it but the physics behind the same is not very much clear to me. How can it (-ve ref. index property) be used in this design?

Can anyone tell me plz?


Regards,

rahul
