报道了一种简化的扁平吕尼堡透镜在60 GHz下的波束导向能力。首先描述了用变换电磁法设计透镜，然后讨论了用陶瓷复合材料铸造制造透镜。仿真显示了波束导向性能，表明该透镜只有6层，最高介电常数为12，在57至66 GHz的带宽范围内实现了30°的扫描角和至少18 dBi的增益。为了验证模拟结果并进一步展示该镜头的宽带特性，原始高清视频通过无线链路以高达36°的扫描角度传输。
The beam-steering capabilities of a simplified flat Luneburg lens are reported at 60 GHz. The design of the lens is first described, using transformation electromagnetics, before discussion of the fabrication of the lens using casting of ceramic composites. The simulated beam-steering performance is shown, demonstrating that the lens, with only six layers and a highest permittivity of 12, achieves scan angles of 30° with gains of at least 18 dBi over a bandwidth from 57 to 66 GHz. To verify the simulations and further demonstrate the broadband nature of the lens, raw high definition video was transmitted over a wireless link at scan angles up to 36°.
