View Full Version : negative I.O.R.

10-28-2006, 07:22 AM
I read a recent Scientific American essay, speaking about metamaterials with negative IOR. Very interesting. I try to obtain such strange images with LW but I noticed that IOR range doesn't allow me to set negative value. It is an understandable choice, cause no natural material has this kind of IOR. But I'd like to simulate ... metamaterials :)
Maybe I read a similar thread a lot of time ago, but I can't find it.
Many thanks

has a good explanation if anyone is interested.

thank you. It's the same I read in Scientific American / Le scienze.
I hope we can achieve the goal with LW. In the paper I read that Veselago used ray trace algorithms to indagate this strange light behaviour.
