Özet

We investigate a nano-aperture based plasmonic metamaterial by integrating the U- and T-shaped nano-aperture antennas in a compact geometry. We experimentally and numerically demonstrate the physical origin of the multi-resonant behavior of the UT-shaped nano-aperture based metamaterials. We also determine the parameter dependence of the proposed nano-aperture antennas. Due to its compact geometry, multi-spectral response, and enhanced near field distributions, our design offers greater flexibility in applications of subwavelength lithography, wavelength-tunable filters, optical modulators, ultrafast switching devices, and biosensing. © 2011 IEEE.
