WebNov 15, 2016 · Metamaterials are promising for a couple reasons. First, they enable the extreme miniaturization of existing optical devices. For example, we can take an eyeglass lens and we can make it 100 times thinner than a strand of hair. This allows us to translate traditionally bulky optical systems to extremely small form factors.
