Based on metallic split- ring resonator, the thermally tunable multi- bands terahertz wave modulator has been designed, while the thermosensitive indium antimonide (InSb) has been further embedded in the gap and the side of the split- ring resonator. On the basis, the variation of the electromagnetic properties of indium antimonide with the temperature has been studied first, and then the influence of the number of the equivalent inductance on the number of resonance frequency has been investiagated. Meanwhile, the variation of the modulation characteristics of the terahertz wave with different embedded ways has also been discussed quantitatively. The results show that the intrinsic carrier density and the plasma frequency of indium antimonide both increase with the increasing of the temperature from 160 to 350 K, while the effective permittivity decreases with the increasing of the temperature. According to the relationship between the resonance frequency and the effective permittivity, the resonance frequency of the modulator can be tuned by varying the temperature. Furthermore, there are two resonance bands for the presence of one equivalent inductance, and five resonance bands can further be achieved when the equivalent inductance further increases to four. Hence, the number of the resonance band increases with the increasing of the number of the equivalent inductance. For the two equivalent inductance modulator embedded by indium antimonide only in the side of the split- ring resonator, the modulation of resonance frequency and resonance amplitude is not obvious with the increasing of the temperature from 160 to 350 K, whereas the first resonance frequency increases significantly and the second resonance band disappears gradually with the increasing of the temperature for the case of the modulator embedded by indium antimonide only in the gap of the split- ring resonator. However, the modulation effects of the resonance frequency and the resonance amplitude of the terahertz wave become obviously with the increasing of the temperature from 160 to 350 K when the indium antimonide is embedded both in the gap and the side of the split- ring resonator. The resonance frequency of the different resonance bands increases evidently with the increasing of the temperature. The transmission magnitude of the first resonance frequency increases at first before decreasing with the increasing of the temperature while the others increase with the increasing of the temperature. Consequently, the thermally tunable multi- band terahertz metamaterial can be applied to multi- bands filter or other frequency selective terahertz device.
