摘要：
The spot of near-field Fresnel zone plate (NFFZP) is very important in electromagnetic field. In this paper, an NFFZP which has been designed to focus a spherical wave at a spot is measured, and the formula for the steered near-field spot of the NFFZP versus frequency is presented and proved. Furthermore, the W-3dB and sidelobe level (SLL) of the spot are characterized. All the results are verified by full-wave simulations and experiments in Ku-band.
