There's been some excitement lately with scientists in the UK revealing that they've been able to use meta-materials to create a positive Casimir Force. This got me thinking that if gravitons have a wavelength would it be possible to create a metamaterial that would have a negative refraction index for them?

I don't think that gravitons can be refracted at all, much less negatively refracted.

The ability to bend gravity at all would violate conservation of energy. If you bent gravity into a loop, an object placed into that loop could be made to accelerate indefinitely with no outside input of energy. It would be a true free-energy device, and a contradiction of conservation of energy.

Gravitons exist in theory only, they have not been detected as yet.
