摘要: 论文研究YVO4中负折射的相关定量细节，以利用该结果设计新型晶体波导结构。利用e光在单轴晶体表面的折射公式，得到入射角、折射角、光轴取向角变化对负折射现象的影响：折射角随入射角增大而增大，随光轴取向角的增大先减小后增大再减小，真空与YVO4界面最大负折射角的最佳光轴取向角为46.43˚。单轴晶体负折射可用于隐身技术中，利用两块光轴对称取向的YVO4孪晶结构可引导e光绕行一定范围或偏折一定的角度。定量的负折射实现条件、入射角及折射角范围，以及孪晶结构的光线偏折现象对YVO4晶体都有定量指导意义。
Abstract: This paper investigated the negative refraction details in YVO4 crystal in order to design new wave-guide. When e-light incidents on the interface of uniform media and uniaxial crystal, the refracted and incident rays may be on the same side of the normal line, which is negative refraction. The formula for e-light refraction was given in this paper. As a special uniaxial crystal with good optical characteristics and obvious birefrigence, YVO4 was researched in detail about the influence of the optical axis direction, the area of incident and refracted angles on negative refraction. And negative refraction can be used in stealth technology. In addition, twin-crystal structure was used to guide e-light to bypass some area or to bend some angle. The quantitative results of negative refraction and the twin crystal structure showed new lights on the application of negative refractions of YVO4 crystal.
