Abstract :
This paper calculates the S-parameters of the metamaterial structure using finite element simulation. To verify the simulation, a slab composed of arrays of the Omega structures was prepared, and the S-parameters of the metamaterial slab sample were measured using a focused beam free-space microwave measurement setup. The direct comparison of S-parameters shows perfect agreement of the simulation and the measurement. A strong resonance at about 7.5 GHz is observed
