摘要
折射和反射是波动传播时的基本现象,光波、电磁波和声波等均可被材料界面折射和反射。近来研究发现,通过在界面上制备人为设计的亚波长结构阵列,可改变传统折射和反射行为,为成像、电磁/几何外形解耦、全息显示等技术提供新的手段。本文综述了近年来折反射定律研究取得的进展,介绍了不同材料体系中波的折反射行为,阐述了相关的基本理论和具体应用。最后,结合本课题组的最新结果,分析了现有研究存在的不足,展望了本领域未来的发展趋势。
Abstract
The refraction and reflection are basic phenomena in the propagation of all kinds of waves, such as light waves, electromagnetic waves and acoustic waves, when they encounter the interface between different kinds of materials. Recently, it is discovered that the traditional optical laws regarding refraction and reflection can be rewritten when artificially designed subwavelength arrays are fabricated on the interfaces. The revised laws provide promising alternatives to achieve imaging, multi-physics decoupling and holographic display. Here we review the recent progresses in this emerging topic, including the refraction and reflection behavior in various materials configurations, the fundamental theories and practical applications. Finally, based on our recent results, the shortcomings of current researches are analyzed with a look towards the future trends of the overall area.
