High-transmissivity composite left/right-handed uniaxial bulk metamaterials were fabricated in a multilayered dielectric/hole metal array technology and experimentally assessed at submillimeter wavelengths (0.4–0.9 THz) by time-domain spectroscopy. From the frequency dependence of the complex scattering parameters, we show the possibility to close the gap between the left- and right-handed dispersion branches by increasing the number of layers from 3 to 5. Such a demonstration paves the way of balance composite propagation characteristics with a gapless transition between the negative and positive values of refractive index at a frequency of 0.5 THz
