RESEARCH ON THE CAUSTIC CHARACTERISTICS OF ONE DIMENSIONAL FRESNEL ZONE PHASE CORRECTED PLATE REFLECTOR
一维菲涅尔区相位修正平面反射器的聚焦特性研究

One dimensional Fresnel zone phase corrected plate (1-DFP) can be made by a 1/P wavelength phase correcting along one dimension upon the plate. When it is used as a reflector, it gives an alternative to parabolic cylinder reflector in application on fan-beam antenna. In this paper, Physical Optics (PO) is used in analyzing the caustic characteristics of 1-DFP reflector with plane wave illumination. Numerical results of a series of fields in caustic are also presented.
