Simulated Output Images of Near-Field Optics by Volume Integral Equation: Object Placed on the Dielectric Substrate

Simulation of confined and enhanced optical near-fields for an I-shaped aperture in a pyramidal structure on a thick metallic screen

“…Equation ͑1͒ has been applied to a number of NFO problems, and has revealed numerous interesting findings. [13][14][15][16][17][18][19] For the problem shown in Fig. 1, however, the volume integral region V has an infinite volume, making it impossible to apply Eq.…”
