Negative index materials are artificial structures whose refractive index has negative value over some frequency range.
The study of these materials has attracted a lot of attention in the scientific community not only because of their many potential interesting applications but also because of challenges in understanding their appealing properties due to the sign-changing coefficients in equations describing their properties. In this talk, I give a survey on recent mathematical progress in understanding applications and properties of these materials. In particular, I discuss superlensing and cloaking using complementary media, cloaking an object via anomalous localized resonance, the possibility that a lens can become a cloak and conversely, and various conditions on the stability of these materials.
