Abstract

A method to design and realize the beam-steerable lens is proposed and tested in this paper. Such a lens is composed with varactor-diodes-loaded metamaterials. The electromagnetic properties of the lens, in particular, the refractive index distribution, can be controlled by reverse bias voltages added to the metamaterials. Therefore, the lens obtains flexible beam forming functions when a variety of reverse bias voltages are applied. A prototype of the lens is manufactured, and its beam-forming function is successfully demonstrated in experiment.

一种使用变容二极管的光束可操纵的超材料透镜

本文提出了一种可调光束透镜的设计与实现方法，并对其进行了测试。这种透镜由负载变容二极管的超材料组成。透镜的电磁特性，特别是折射率分布，可以通过向超材料中添加反向偏置电压来控制。因此，当施加各种反向偏置电压时，透镜获得灵活的光束形成函数。制作了该透镜的原型，并在实验中成功地验证了其波束形成功能。
