Paper Abstract

In this paper we study the propagation of light through silver-dielectric metamaterial layered prism which operates in the canalization regime. The prism is illuminated with TM-polarized light and is designed using the effective medium theory as strongly anisotropic and impedance matched to air. The structure has an infinite value of the effective permittivity in the direction perpendicular to layer surfaces. Therefore it is able to couple a broad spectrum of incident spatial frequencies, including evanescent waves, into propagating modes. As a result, subwavelength resolution at the output interface of the structure is observed. Further the device is characterised with the transfer matrix method (TMM), and investigated with Finite Difference Time Domain method (FDTD). Two parameters of the prism are studied, namely the angle of incidence and the apex angle, to obtain the best resolution.
