    Abstract:
    Limitations on subdiffraction imaging with a negative refractive index slab was studied. The planar geometry allowed a straight forward analysis to be implemented. The fields from an arbitray electromagnetic source were expanded in a Fourier series over homogeneous and inhomogeneous plane waves. The sensitivity of subwavelength focus to the slab material properties, periodicity and its connection to slab surface plasmon modes were studied. It was concluded that significant subwavelength resollution was achievable with a single negative index slab, only over a restrictive range of parameters.
