By arranging the nanoscale unit cells in a desired geometry, the refractive index of the metamaterial can be adjusted to positive, near-zero, or negative values. Among the most sought-after properties ...

Now chirality in man-made metamaterials that is orders of ... As a result, the refractive index can be negative even though the permittivity and permeability are not simultaneously negative ...

Alexander Popov and Sergey Myslivets have now proposed a new approach to overcome losses in metamaterials over the entire negative-index frequency range 1.The proposed technique is based on a well ...

In this graduate survey course, we will discuss the structure, properties, and applications of metamaterials including photonic bandgap materials, negative index materials, digital alloys, and quantum ...
