Surface plasmon resonance of two segmented Au Cu nanowires in polycarbonate template

Two segmented gold copper nanowires were grown inside the pores of polycarbonate track (PCT) etched membranes from two separate solutions by electrodeposition method. Optical absorption spectra of two segmented Au Cu nanowires in PCT template were shown a surface plasmon- polariton peak appeared at about 900 nm for incident angle of theta = 65 degrees but for theta= 0 there are not any peaks in spectra.
