Natural diamagnetism, while being a common phenomenon, is limited to permeability values close
to unity. Artificial diamagnetics, to the contrary, can be engineered to provide much lower values
and may even possess an effective permeability close to zero. In this letter, we provide an
experimental confirmation of the possibility to obtain extremely low permeability values by
manufacturing an isotropic metamaterial composed of conducting cubes. We show that the
practical assembly is quite...[Show more]
