Abstract
In the paper, we report about the possibilities to apply the photon sieve principle to binary diffractive lens in millimeter wave band. The FDTD simulation showing the idea of the photon sieve application to millimeter wave optics does not allow increasing the resolution power. The reason is the small number of holes in the FZP aperture. But such simulation results may be used as computational experiments of simple scale in millimeter wave allowing obtaining insight into physical systems which are characterized by nanometric objects, because the D/f and D/λ are almost the same.
Highlights
According to the IEEE Standard Definition of Terms for Antennas (IEEE Std 145-1993), Fresnel lens antenna is an antenna consisted of a feed and a lens; usually Planar transmits the radiated power from the feed through the central zone and the alternate Fresnel zones of the illuminating field on the lens
Unlike a zone plate which is composed of concentric rings, a photon sieve is composed of a great number of pinholes suitably arranged according to the ring pattern of a classical Fresnel zone plate

Summary
According to the IEEE Standard Definition of Terms for Antennas (IEEE Std 145-1993), Fresnel lens antenna is an antenna consisted of a feed and a lens; usually Planar transmits the radiated power from the feed through the central zone and the alternate Fresnel zones of the illuminating field on the lens. Spatial resolution of the conventional diffractive lenses, such as Fresnel zone plate, is in the order of the width of the outmost zone. Unlike a zone plate which is composed of concentric rings, a photon sieve is composed of a great number of pinholes suitably arranged according to the ring pattern of a classical Fresnel zone plate. Taken into account that in millimeter wave band, the number of Fresnel zones at the FZP aperture is small [4,5,6,7,8], and the effect of photon sieve to resolution power is not the evidence and has not been published in the literature yet. We report about the possibilities to apply the photon sieve principles to diffractive lens in millimeter wave band
