    "abstract": "Dispersion, impedance matching and resolution characteristics of an isotropic\nthree-dimensional flat lens (\"superlens\") are studied. The lens is based on\ncubic meshes of interconnected transmission lines and bulk loads. We study a\npractical realization of the lens, based on the microstrip technology. The\ndispersion equations that have been previously derived, are verified with\nfull-wave simulations. The isotropy of the structure is verified with\nanalytical as well as simulation results. The resolution characteristics of a\npractically realizable, lossy lens are studied analytically.",
