大多数天线被制成碟形，用以收集和反射无线电波至亚反射器，就像曲面镜将可见光聚焦于一点一样。
Most antennas are made in the shape of a dish to collect and reflect the radio waves to the sub reflector, in the same way as a curved mirror focuses visible light to one point.
他们的新型天线在其他需要光聚焦的领域同样可能得到较为广泛的应用，如夜视镜，望远镜等。
Their new antennas might also be useful for any other application that requires light to be concentrated, such as night-vision goggles or telescopes.
碳纳米管组成天线，用来捕获并聚焦光的能量，这就意味着更加小体积而高效电池组件将在不久的将来诞生。
Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays.
