Abstract :
The EM polarization properties of the active cylindrical coated nano particle antennas are investigated in the visible frequency band. It is observed that the active cylindrical coated nano particle could be illuminated by plane waves with horizontal polarization or vertical polarization, and show the dipole mode, although the resonant size of the particles are little different. Especially, when the vertical polarization plane wave incident to the particle with 45° rotation angle, it still show the dipole mode, the electrical field and power flow are symmetrical along the particle axis, and looks like a combination of the horizontal polarization mode and vertical polarization mode.
