Resumen

This paper presents a novel type of characterization for 3D fully-dielectric unit cell. The unit cell structure is formed by a block of dielectric with different inserts of air on it. The performed characterization is carried out up to the frequency where the electric-size of the unit cell is λ/2. Based on the results obtained in simulation, design equations for the effective permittivity can be extracted for the two different dielectric unit cell designs. Using equivalent circuit, several arrangements of dielectric unit cells have been modelled. The results obtained with the circuit models are in good agreement with the simulated S parameters in a wide frequency range.
