摘要：

The fields in the focal space of two types of a phase-only diffractive lens, which is illuminated by a plane wave, are analyzed with the FDTD method and the Stratton-Chu formula. Both oblique and perpendicular incidence are considered. The diffraction efficiency is calculated. The results of experiments carried out to verify the correctness of the calculation are presented.
