一维透射式菲涅尔区相位修正结构的辐射特性

On the Radiation Characteristics of One dimensional Fresnel Zone Phase Correcting Plate Lens

一维菲涅尔区相位修正结构具有类似于抛物柱面的聚焦特点。本文应用口径场法对透射式一维菲涅尔区相位修正结构的辐射特性进行了分析，并在９ＧＨｚ频率上进行了辐射方向图的测量。

One dimensional Fresnel zone phase correcting plate has its focusing characteristics similar to that of the paraboloid cylinder. In this paper, the radiation of such FZP lens is analyzed both theoretically and experimentally at 9GHz. The theoretical results calculated by aperture fields give good agreements to the experimental ones, and both present the good paraxial scanning properties of the lens.
