Embodiment 1
[0049] Use the CST simulation software to simulate the design of the terahertz wave modulator, select the time domain solver for calculation, the calculation accuracy is -80dB, obtain the S parameters of the THz wave modulator based on the Dirac semi-metallic microstructure, and obtain the transmission spectrum line according to the S parameters , reflection lines and absorption lines, the specific formulas are as follows:
[0050] T(ω)=|S 21 (ω)| 2
[0051] R(ω)=|S 11 (ω)| 2
[0052] A(ω)=1-T(ω)-R(ω)
[0053] Among them, S 21 (ω) and S 11 (ω) are the transmission coefficient and the reflection coefficient, respectively, and T(ω), R(ω) and A(ω) are the transmission line, reflection line and absorption line, respectively.
[0054] like image 3 As shown, the structural unit of the Dirac semimetal microstructure 4 is elliptical, the semi-major axis and semi-minor axis are 40 μm and 15 μm, respectively, the period of the metamaterial structural unit is 108 μm, and the Fe...
