Abstract

We present a dualband terahertz metamaterial based on a hybrid 'H'-shaped cell of different sizes. The proposed 'H'-shaped metamaterial (HSM) structure, fabricated on a quartz (SiO₂) substrate, exhibits two intense electrical resonances at ~0.95 THz and ~1.26 THz, respectively. Extracted effective permittivity show negative values in 0.95-1.01 THz and 1.26-1.42 THz bands. Measured results from the terahertz time-domain spectroscopy (THz-TDS) experiments show good agreement with the simulated results.
