Rotational Displacement of Optical Intensity by Linear Polarisation in Nano Antenna

Abstract

in nanoantennas was made using finite difference time domain. In this study analysis of simulation was used. It was found that rotationally displayed distribution of intensity occurred near excitation field for each linear polarization. This finding contributed circular polarization for phase distribution. The creation of phase distribution was found due to superposition of plasmonic modes. Phase distribution produced rotational displaced intensity distributions around square antenna. Square nanoantennas and electric intensity was found isotropic at longer wavelength. It was found that intensity distribution was found in the direction of electric field rotation for light of shorter wavelength.
