Abstract :
We computationally investigated the optical properties of a thin metallic aperture, emphasizing the effects of the dielectric substrate on the plasmonic waveguide. We demonstrate that the red-shifted wavelength and the dielectric properties (i.e., effective relative permittivity and dielectric thickness) can compensate for the optical loss due to plasmon red shift.
