A Dual-Band Terahertz Metamaterial Based on a Hybrid 'H'-Shaped Cell

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