Abstract：A fishnet structure of zero-index metamaterial composed of a square metal ring， square pieces of metal and cross wire is proposed. The simulation calculation and retrieved results indicate that the effective permittivity and permeability of the proposed structure close to 0 at the frequency of 11.54GHz when normal linearly polarized wave incidence directly， and the experimental results coincide with the simulation results. Through a prism simulation， the simulation calculation results support the idea of where the zero-index frequency point should be generated， the transition from a negative-n region to a positive-n region. Thus， the result demonstrates that the proposed structure indeed exhibits a balanced property with a negative-zero-positive behavior.
