Effects of disorder on superlensing in two dimensional photonic crystal slabs
Abstract
We demonstrate that a hexagonal two dimensional photonic crystal can act as an isotropic medium with an effective refractive index neff = -1, therefore capable of unrestricted superlensing. We study the superlensing by calculating the photonic band structure, and the propagation maps of the electromagnetic waves through slabs of the photonic crystal. We investigate the surface, and the crystal disorder effects on the superlensing, by analyzing the light intensity profile at the image of a line source.
