We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain uniform refraction property, in both the near- and far-field cases. In the near-field problem, unlike the case when both materials have positive refractive indices, we show that the resulting surfaces can be neither convex nor concave.
我们研究构建一个分隔两种均匀、各向同性介质的光学表面的问题，其中一种介质具有负折射率。在此过程中，我们推导出了斯涅尔定律的矢量形式，该形式用于研究在近场和远场情况下具有特定均匀折射特性的表面。在近场问题中，与两种材料都具有正折射率的情况不同，我们表明所得到的表面既非凸面也非凹面。
