Abstract:
Strong polarization dependence in the optical transmission through a bull's eye with a central elliptical aperture in a thin Au film is analyzed numerically by finite difference time domain (FDTD) method. Focusing on the impacts of the structural anisotropy, detailed investigation of polarization dependent enhanced optical transmission (EOT) of light is discussed in terms of the resonance intensity variations caused by the incident light polarization and the geometrical parameters of bull's eye. We found that the light polarized along the minor axis of the elliptic aperture has significantly larger EOT by more than three orders of magnitude than the other orthogonal polarization, which can be further utilized in polarized EOT devices.

Electric Field of a Charged Disk
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...
