I am new to the forums, so hi. I have been woundering about meta materials. From what I know, meta-materials are extremly small objects that are able to bend light because of their unique shapes. Some have demonstrated how they can be placed to cause an invisibility cloak by having the light bend around the object so the light goes around and out at the same place it would have if the object was not there. The question I have been thinking about is whether you can use meta materials to bend light around the object completly, so the light just keeps going in a circle around the object. I thought of this because a professor, Ronald Mallett, is using light to bend space and time. So could meta-materials be used to do the same thing?
