Figure 6: Two-dimensional absorption maps displaying absorbed power in metal.
(a) Three-dimensional view of simulated absorber structure with cross-sections along the top Ag/SiO2 (orange plane) and bottom SiO2/Ag layer (grey plane). (b) Schematic drawing of the metallic section (first column) at z=160 nm (top row) and z=100 nm (bottom row), and corresponding 2D absorption maps at three extinction peak wavelengths, 475 nm (second column), 560 nm (third column) and 630 nm (fourth column). (c) yz cross-sections at two different x positions, x=150 nm (red plane) and x=300 nm (purple plane). (d) 2D absorption maps in metallic portion for the indicated yz plane positions at the peak wavelengths. Graphs in b and d are plotted in logarithmic scale, and red colour corresponds to higher absorption.
