Effects of disorder on subwavelength lensing in two-dimensional photonic crystal slabs
Effects of disorder on subwavelength lensing in two-dimensional photonic crystal slabs
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 superlensing. We study the superlensing by calculating the photonic band structure, and the propagation maps of the electromagnetic waves through slabs of the …
