新形式光波只朝一个方向行进有望带来更高效光纤 据物理学家组织网3日报道，来自英国爱丁堡大学和美国宾夕法尼亚州立大学的科学家和工程师，分析了以波的形式传播的光与某些天然或人造晶体之间的相互作用，发现了这种新形式的波。 他们发现，季亚科诺夫·福格特波产生于一个特定区域，即晶体与另一种物质（如油或水）相遇的界面。研究人员说，这些波只能由特定类型的晶体产生，这些晶体的光学特性取决于光通过它们的方向。 自19世纪中期以来，有关光与晶体相互作用的研究都建立在麦克斯韦的工作基础上。在最新研究中，团队成员利用数学模型，结合由麦克斯韦开发的方程式，确定了这种光波的独特性质。 研究小组发现，以两位著名科学家的名字命名的季亚科诺夫—福格特波，在远离界面（这个过程被称为衰变）时会减弱，并且只朝一个方向行进。而其他类型的所谓表面波衰减更快，并向多个方向传播。 相关研究发表于最近的《英国皇家学会学报A》。论文共同作者、爱丁堡大学数学学院的汤姆·麦凯博士说：“季亚科诺夫—福格特波代表我们在理解光与复杂材料如何相互作用方面向前迈进了一步，也为一系列技术进步奠定了基础。” 相关链接：相关链接：https://phys.org/news/2019-09-eminent-scientist-year-old-theories-aid.html 关键词： 光纤

A previously unknown type of light wave has been discovered by researchers, based on the pioneering work of a 19th century Scottish scientist.
Equations developed by renowned mathematician and physicist James Clerk Maxwell have helped to reveal how crystals can be manipulated to produce a distinctive form of light wave.
The phenomena – recently named Dyakonov-Voigt waves – could have a range of useful applications, such as improving biosensors used to screen blood samples or developing fibre optic circuits that transfer data more efficiently.
Wave discovery
Scientists and engineers from the University of Edinburgh and Pennsylvania State University made the discovery by analysing how light – which travels in the form of waves – interacts with certain naturally occurring or man-made crystals.
They found that Dyakonov-Voigt waves are produced at a specific region – known as an interface – where the crystals meet another material, such as oil or water.
These waves can be produced only using certain types of crystal whose optical properties depend on the direction in which light passes through them, researchers say.
Original equations
The team identified the waves’ unique properties using mathematical models that incorporated equations developed by James Clerk Maxwell. Since the mid-1800s, research on how light interacts with crystals has built on the work of Maxwell, who studied at the University of Edinburgh from the age of 16.
Dyakonov-Voigt waves, named after two leading scientists, diminish as they move away from the interface – a process called decay – and travel only in a single direction, the team found. Other types of so-called surface waves decay more quickly and travel in multiple directions.
