The Fresnel Zone-Plate Lens

James C. Wiltse

Open publisher page 42 citations

Abstract

A description is given of the use of the Fresnel zone plate as a focusing or a frequency-filtering device at millimeter wavelengths. Sample design data are given, as well as references to prior results. A newer type of zone plate is discussed which employs two dielectrics of equal thickness to produce a flat zone plate.
