      Planar refraction and lensing of highly confined polaritons in anisotropic media 

      Duan, J.; Álvarez Pérez, G.; Tresguerres Mata, ‪Ana I. F.; Taboada Gutiérrez, J.; Voronin, Kirill V.; Bylinkin, Andrei; Chang, B.; Xiao, S.; Liu, S.; Edgar, James H.; Martín, J. I.; Volkov, Valentyn S.; Hillenbrand, Rainer; Martín Sánchez, J.; Nikitin, Alexey Y.; Alonso González, P. (Nature, 2021-07-15)
      Refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- to a high-refractive-index medium. However, refraction between anisotropic media is a more ...
