Summary: | We review conducting materials like metals, conducting oxides and graphene for
nanophotonic applications. We emphasize that metamaterials and plasmonic systems
benefit from different conducting materials. Resonant metamaterials need
conductors with small resistivity, since dissipative loss in resonant
metamaterials is proportional to the real part of the resistivity of the
conducting medium it contains. For plasmonic systems, one must determine the
propagation length at a desired level of confinement to estimate the dissipative
loss. |
