| Abstract(in English) | The Fresnel zone plate (FZP) is analyzed in visible light using the body-of-revolution finite-difference time-domain (BOR-FDTD) method. First, we compare the properties of an odd and an even type FZP for a lin-early polarized incident wave. For the odd type, high focusing properties are obtained by the proper choice of thethickness of the FZP, when compared with the even type. To show the effect of the surface plasmon polariton, we analyze the FZP consisting of a perfect electric conductor. The use of the FZP consisting of the dispersive medium (silver) contributes to high concentration of the field. Next, we analyze FZPs for a radially polarized incident wave. The E_z component is concentrated on the central axis for each of FZPs. Finally, we compare the result obtained for the radial polarization with that for the linear polarization. It is found that the radial polarization serves to enhance the E_z component on the central axis with the reduced E_p component around the axis. |
