Metamaterial hyperlenses are novel devices that utilize the unique dispersion properties of hyperbolic metamaterials to resolve subwavelength images. Stacked wire media hyperlenses have been shown to possess advantages over conventional wire media hyperlenses since they decouple the lens length from operating frequency, and broaden the operating bandwidth. We investigate these devices using both a transfer matrix method and tight binding approximation to find the modes in the effective medium regime. We then use semi-analytical and numerical techniques to find the limitations of the analytical model, and gain insight into the regime beyond these limits. We also investigate the modes of stacked WM slabs consisting of dielectric coated wires and discuss potential applications of such structures.
