摘要：

The design, fabrication and measurement of a broad/dual-band terahertz (THz) metamaterial based on gallium arsenide substrate are presented. The proposed Modified Split-Ring Resonator (MSRR) provides two distinct strong electrically resonances near 0.515 THz and 0.74 THz. Effective medium parameters show negative values of permittivity during two broad frequency bands of 0.492-0.693 THz and 0.727-0.811 THz. Measured results obtained from the Terahertz time-domain spectroscopy (THz-TDS) show good agreement with the simulation results. This metamaterial is expected to enhance the realization of broadband and multi-band functional materials and devices in THz regime.
