ABSTRACT
The nanowires with diameters in the range of 100 nm were prepared by electrochemical deposition in polycarbonate etched ion-track membranes and transferred onto infraredtransparent substrates. For a few microns long nanowires, antenna-like plasmon resonances were observed in agreement with light scattering calculations. The resonances are dependent on wire length, wire shape, and on the dielectric surroundings of the nanowire. Electromagnetic far-field enhancement at resonance points to the ability of the nanowire to confine light on the nanoscale. This effect can be exploited for surface enhanced infrared absorption.
