Document Type and Number:
WIPO Patent Application WO/2020/191911
Kind Code:
A1
Abstract:
Provided in the present invention is a novel method for producing a Luneburg lens, which may produce high-performance Luneburg lenses that have stable indexes under the conditions of room temperature, normal pressure and low costs. The method comprises the following steps: preparing a half housing as a lens half housing, spraying an adhesive on an inner wall surface of the lens half housing, coating a prefabricated first particulate material into the lens half housing, using a punch to press the first particulate material to form a first dielectric layer, spraying the adhesive on a surface of the first dielectric layer, coating a second particulate material on the surface of the first dielectric layer and pressing, and so on to produce a half Luneburg lens, and then bonding two half Luneburg lenses together to form a Luneburg lens. The described method for producing the Luneburg lens of the present invention has the advantages of a simple production process, low production costs, a light mass, easy control of lens characteristics, excellent lens performance indexes, etc.
