Dispersion, impedance matching and resolution characteristics of an isotropic three-dimensional flat lens ("superlens") are studied. The lens is based on cubic meshes of interconnected transmission lines and bulk loads. We study a practical realization of the lens, based on the microstrip technology. The dispersion equations that have been previously derived, are verified with full-wave simulations. The isotropy of the structure is verified with analytical as well as simulation results. The resolution characteristics of a practically realizable, lossy lens are studied analytically.
