Negative Refraction and Subwavelength Lensing in a Polaritonic Crystal
X. Wang, K. Kempa
We show that a two-dimensional polaritonic crystal, made of metallic rods that support well defined plasmon oscillations, can act in a narrow frequency range as a medium in which a…

Improved superlensing in two-dimensional photonic crystals with a basis
X. Wang, Z. F. Ren, K. Kempa
We study propagation of light in square and hexagonal two-dimensional photonic crystals. We show, that slabs of these crystals focus light with subwavelength resolution. We propose…

Effects of disorder on superlensing in two dimensional photonic crystal slabs
X. Wang, K. Kempa
We demonstrate that a hexagonal two dimensional photonic crystal can act as an isotropic medium with an effective refractive index n_eff = -1, therefore capable of unrestricted sup…
