We implement a two-dimensional Maxwell’s fish eye lens using a waveguide-based artificial dielectric. The Maxwell’s fish eye lens consists of two metallic cylindrical plates sandwiching a free-space region, with the inner surface of one plate shaped into a hollow conical form. This lens has the capability to image terahertz beams from a source located at the edge (between the plates) to the diametrically opposite point on the edge, independent of the incident angle
