A lens translating a near-field pattern from an almost circular input boundary onto a magnified far-field image at a flat output boundary is considered. The lens is made of a metamaterial with anisotropic permittivity and permeability both depending on a single 'scaling' parameter of the transformation. Open designs of the lens with a truncated body ('3/4-body' and '1/4-body' lenses) are suggested and analyzed. It is shown that the ideal full-lens and the '3/4-body' lens produce identical images. Numerical simulations of '1/4-body' designs indicate that further truncation of the lens could limit its per-formance. A light concentrator, "focusing" far-zone fields into a nanometer-scale area, is also considered.
