摘要

菲涅耳带片是具有透镜状聚焦特性的平面器件。平面结构使带板易于构造，并提供较低的吸收损失和重量。本文报道了用金属构造菲涅耳带片。在过去，典型的带板是由介电材料制成的。除了前面提到的优点，金属带板可以机械加工或直接铸造成扇形角。

Metallic zone plates for sectoral horns

Fresnel zone plates are planar devices with lens-like focusing properties. The planar structure makes a zone plate easy to construct and provides lower absorption loss and weight. This paper reports on the Fresnel zone plates to be constructed from metal. Typically in the past, zone plates have been fabricated from dielectric material. In addition to the advantages mentioned earlier, metallic zone plates can be machined or cast directly into sectoral horns.
