Abstract:

Using the transfer-matrix method, we investigate the surface polaritons and imaging properties of a multi-layer structure consisting of alternating positive- and negative-refractive-index materials. It is shown numerically that the amplification of evanescent waves is due to the excitation of the surface polaritons. Moreover, we make a detailed investigation of how the variations in the real parts of the permittivity and permeability and the absorption of negative-n materials affect the image quality. The image quality of a lens made of a multi-layer structure is generally improved in comparison with that of a single slab. Our investigation may be useful for near-field imaging by the lens of such a multi-layer structure if the negative-n materials are necessarily dispersive.
