1. The document studies the mesh field and rotation in various planes of optical spherical nano antennas through mesh field analysis and three-dimensional polarization pattern analysis. 2. It measures the three-dimensional polarization patterns for near fields and far fields of right-hand circular polarization and left-hand circular polarization. The patterns show the antenna's capability to rotate in different planes. 3. Mesh analysis of the electric field, magnetic field, and current density on the antenna's outer surface is presented, showing enhanced field strength near the surface. The analysis provides insight into the antenna's performance and field visualization.
