Popis:	We present a simple masked thermal evaporation technique to fabricate arrays of wirelike Ag microstructures of width 8μm with an extremely high aspect ratio on either silicon or glass substrates. In accordance with the theory of periodic arrays of thin wires, the electromagnetic response of Ag microstructures has shown a characteristic low-frequency plasmonic behavior with a transparent visible region. Plasmon absorption is observed to be splitted largely into transverse and predominating longitudinal bands at near-ultraviolet (415nm) and midinfrared wavelengths (2867nm), corresponding to the oscillation of the free electrons perpendicular to and along the long axis of the wires.
