(a) Simulations as periodicity changes from 1.5 μm to 2.5 μm at a fixed diameter of 1 μm. (b) Simulations as diameter changes from 0.8 μm to 1.2 μm at a fixed periodicity of 2 μm. (c) Simulation results of Au MHAs with a fixed ratio 0.5 for aperture diameter to period. (d) Top view of the simulated E-field distribution inside the holes at peak position.
