Oriented Asymmetric Wave Propagation and Refraction Bending in Hyperbolic Media
Rair Macêdo, Thomas Dumelow, Robert E. Camley +1
Crystal quartz is a well-known anisotropic medium with optically active phonons in the THz region where hyperbolic phonon-polaritons can be excited. Here, we use this material to i…

Far Infrared Slab Lensing and Subwavelength Imaging in Crystal Quartz
R. Estevâm da Silva, R. Macêdo, T. Dumelow +3
We examine the possibility of using negative refraction stemming from the phonon response in an anisotropic crystal to create a simple slab lens with plane parallel sides, and show…
