Figure 2: Resonant modes supported in Ag-coated CdS nanowires (NWs) under transverse magnetic excitation.

(a) Normalized average intensity (Iω,ave) of fundamental wave (FW)-excited modes in the nonlinear region of Ag-coated (black) and bare (red) NWs. (b,c) Calculated intensity distribution (Iω=|Eω|2) of the mode excited by the FW in Ag-coated (b) and bare (c) NWs (d=230 nm). The white lines depict the SiO2 interlayer.
