Polarization anisotropic transmission through metallic Sierpinski-Carpet aperture array.

چکیده
Extraordinary optical transmission through rectangular Sierpinski -Carpet aperture array on an Ag film has been observed. Attributed to the fractal-featured rectangle array, it exhibits polarization dependence and dual-band transmission simultaneously. In addition, the incident angle invariance transmission displays within a certain angle range, which is quite different from ordinary rectangles. This report provides a way to achieve the polarization-manipulated multi-band transmission in infrared region.

Electromagnetic Transmission through Fractal Apertures in Infinite Conducting Screen
Fractals contain an infinite number of scaled copies of a starting geometry. Due to this fundamental property, they offer multiband characteristics and can be used for miniaturization of antenna structures. In this paper, electromagnetic transmission through fractal shaped apertures in an infinite conducting screen has been investigated for a number of fractal geometries like Sierpinski gasket,...
متن کاملPolarization tomography of metallic nanohole arrays.
We report polarization tomography experiments on metallic nanohole arrays with square and hexagonal symmetry. As a main result we find that a fully polarized input beam is partly depolarized after transmission through a nanohole array. This loss of polarization coherence is found to be anisotropic; i.e., it depends on the polarization state of the input beam. The depolarization is ascribed to a...
