as for refraction being complicated:no it isn't! nor is it anything to do with the incorrect belief that light is a wave.
Would you show me how believing light to be a wave is incorrect?

Ok lets forget about sci-fi usage but if we can get it to make a microscope so we can clearly see an atom, electron, proton or DNA structure. Think what we can do with that info.
We might get a cure for deadly viruses.

I'm not totaly sure I understand negitive refraction index well enoth but from my understanding wouldnt an object covered in a material that has this type of refaction not look invisibile but actualy distorted? Like you would be looking at something to the left or right of your direct vision?

you can only see an object if light is reflected off of it then to your eye. If they can achive what they are working on the light will not reflect but in a sense be passed through the obejct opticaly.

This is fantastic stuff. I have seen the results for the cloaking devices in microwave frequencies, which were able to clock a solid copper rod very well (although not perfectly).

Negative refraction is a little bit harder to grasp. Especially from the materials side of the thing. Designing a photonic crystal or other type of structure to make a meta-material is fairly complicated. Much to complicated for me anyways.

why on earth or anywhere else other than science fiction would anyone want to become blind or invisible? now if it could make blind people "see" then its worth thinking about.
Its science, its motiviation shouldn't be what it can do for people. Science's motivation is that its learning more about the world. If something "tangible" comes out of it too, all the better!
