Figure 1

Experimental set up schematically illustrating the orientations of lithographically patterned gold nanorods aligned perpendicular and with a component parallel to the wave vector. Unpolarized light is directed toward the sample tilted at 30° (θ), thus the sample normal is oriented 30° to the electron beam trajectory and 60° to the photon wave vector. Inset shows magnified views of the nanorods illustrating the aloof positions for (a) horizontal nanorods (b) vertical nanorods and the electric field polarization component that couples to the LSPR modes.
