title: Tunable photonic metamaterials in the near infrared frequencies.
abstract: By using interference lithography and electron-beam evaporation and lift-off, we fabricate a series of pairs of elliptical metal-dielectric-metal plates with varying lengths of major and minor axis. Transmission measurements reveal that the magnetic response of the structures show linear shift with both the axis length of the elliptical plates and polarization direction of the incident light in a region of from 1.26microm to 2.10 microm. Our structures offer opportunities for oversimply constructing bulk photonic metamaterials for various applications.
