Investigation of nanobrick width relations. Calculated complex reflection coefficient, r, as a function of dimensions of the first nanobrick, \(L_{x1}\) and \(L_{y1}\), for system parameters: \(P_x=P_y={330}\,\hbox {nm}\), \(t_m = {70}\,\hbox {nm}\), \(t_s=d_x={60}\,\hbox {nm}\), \(t_b=g={40}\,\hbox {nm}\), \(\lambda _0={900}\,\hbox {nm}\). The color map represents reflection coefficient amplitude and the contours represent reflected phase for normal incident TM polarized light. The separation between phase contours is \({60}^\circ\). The three color maps represent three different relations between the widths of gold nanobricks, namely equal width (left panel), the shorter nanobrick having twice the width (middle panel), and both nanobricks having equal top-surface areas (right panel).
