| Abstract(in English) | Fresnel zone plate (FZP) reflectors are analyzed in visible light using the body-of-revolution finite difference time-domain (BOR-FDTD) method. First, the focusing characteristics are evaluated for a transmission type FZP. The advantage of the use of a dielectric FZP is demonstrated in comparison with a metallic FZP. Next, we compare the result obtained for the transmission type with that for the reflection type. The intensity of the reflection type is increased by a factor of 1.6. We further analyze the FZP based on a staircase approximation. As a result, the intensity which is 1.2 times greater than that observed with a planar structure can be obtained by introducing the staircase approximation. Comparison with a Fresnel lens with a metal reflector shows the validity of the staircase approximation. |
